A website suddenly becoming extremely slow or unavailable can be alarming. The first assumption may be that the server has crashed, the hosting provider has a problem, or the website application has developed an error. However, another possibility is a Distributed Denial-of-Service (DDoS) attack.

A DDoS attack attempts to make a website, server, API, application, or network unavailable by overwhelming it with traffic or requests originating from many systems. The attack may consume Internet bandwidth, connection tables, firewall resources, CPU, memory, application workers, database capacity, or another finite resource.

The important challenge for administrators is that high traffic does not automatically mean DDoS. A marketing campaign, viral social-media post, software update, search-engine crawler, product launch, or legitimate customer activity can also produce a sudden traffic increase.

Cloudflare identifies site unavailability or slowness, unexpected increases in requests or bandwidth, and unusual requests in origin-server logs as common signs that a site may be experiencing a DDoS attack.

Therefore, DDoS detection should be based on multiple indicators rather than a single traffic graph.

What Is a DDoS Attack?

DDoS stands for Distributed Denial-of-Service.

Instead of sending attack traffic from only one computer, an attacker generally uses numerous distributed devices or systems to generate traffic toward the victim.

These devices may include compromised:

• PCs
• servers
• routers
• IoT devices
• cameras
• DVRs
• virtual servers
• cloud systems
• other Internet-connected equipment

Together, compromised devices may form a botnet.

The attacker's objective is usually not to enter the website or steal a password directly. The immediate objective is to interfere with availability—preventing legitimate customers from accessing the service.

DDoS attacks may target different parts of the infrastructure, including the network, transport protocols, DNS infrastructure, web applications, and APIs.

Major Categories of DDoS Attacks

Understanding the attack category helps determine what metrics you should investigate.

1. Volumetric DDoS Attacks

Volumetric attacks attempt to consume the available Internet bandwidth of the target or its upstream infrastructure.

You may observe:

• extremely high bandwidth utilization
• massive packet volumes
• packet loss
• high network latency
• upstream network congestion
• websites becoming unreachable

Large volumetric attacks generally need to be mitigated upstream, before the traffic consumes the victim's Internet connection.

2. Protocol or Network/Transport-Layer Attacks

These attacks attempt to exhaust resources in network infrastructure such as firewalls, load balancers, servers, or connection-tracking systems.

Examples can include:

• SYN floods
• UDP floods
• ICMP floods
• certain reflection/amplification attacks

A server may therefore fail even when CPU utilization does not initially appear exceptionally high.

3. Application-Layer or Layer 7 DDoS Attacks

Application-layer attacks target applications such as:

https://example.com/
https://example.com/login
https://example.com/search
https://api.example.com/

Instead of simply consuming bandwidth, the attacker may repeatedly request expensive application functions.

Examples include repeated requests to:

• search pages
• login pages
• APIs
• database-intensive reports
• dynamic pages
• uncached content
• shopping-cart functions

Application-layer attacks can be particularly difficult to distinguish from legitimate traffic because HTTP requests can resemble normal browser activity.

Cloudflare's HTTP DDoS protection, for example, evaluates suspicious patterns, protocol violations, excessive origin/cache traffic and other Layer 7 attack characteristics rather than relying solely on total bandwidth.

How Can I Tell Whether My Website Is Experiencing a DDoS Attack?

No single symptom proves that an attack is occurring. Administrators should correlate several indicators.

1. Your Website Suddenly Becomes Very Slow

One of the first symptoms may be a dramatic increase in response time.

For example, normal page response:

200–500 ms

may suddenly become:

3 seconds
10 seconds
30 seconds
Timeout

However, this alone does not prove DDoS.

Database problems, application bugs, exhausted PHP workers, storage problems, backup jobs, legitimate traffic, or server overload can produce similar symptoms.

2. Your Website Becomes Completely Unavailable

Visitors may begin receiving:

Connection timed out
Connection refused
Service unavailable
502 Bad Gateway
503 Service Unavailable
504 Gateway Timeout

Availability monitoring may simultaneously report failures from several geographical locations.

This becomes more suspicious when it occurs alongside an abnormal increase in network or HTTP traffic.

3. Requests Per Second Increase Abnormally

Establish the website's normal traffic baseline.

Suppose a website normally receives:

20–100 requests/second

and suddenly receives:

5,000 requests/second

without any corresponding marketing campaign or business event.

That should be investigated.

Do not define a universal threshold such as "1,000 requests per second equals DDoS." A large e-commerce platform and a small corporate website have completely different normal traffic profiles.

Deviation from your own baseline is more meaningful than an arbitrary number.

4. Bandwidth Usage Suddenly Spikes

Monitor:

• inbound bandwidth
• outbound bandwidth
• packets per second
• connections per second
• requests per second

For example:

Normal inbound traffic: 15 Mbps
Current traffic:        900 Mbps

Such an unexplained increase is a strong reason to investigate.

Cloudflare specifically recommends checking unexpected request and bandwidth spikes when investigating a possible DDoS incident.

5. Server CPU Usage Reaches 100%

Application-layer attacks can overload web applications.

You might see:

CPU:       98–100%
Memory:    90–100%
Load:      Extremely high
PHP-FPM:   Workers exhausted
Apache:    Maximum workers reached
Database:  Connections exhausted

But high CPU alone is not proof of DDoS.

A badly optimized database query or software malfunction could produce the same result.

Correlate resource utilization with traffic and logs.

6. Concurrent Connections Increase Dramatically

Monitor active connections on the server, firewall, reverse proxy, and load balancer.

For example:

Normal connections: 500
Current connections: 45,000

A sudden unexplained increase can indicate an attack or another abnormal traffic event.

Connection-state exhaustion can also overload firewalls and load balancers before the application server itself becomes overloaded.

7. Thousands of Requests Target One URL

Examine access logs.

You may discover unusually high traffic toward a specific endpoint:

/login
/search
/wp-login.php
/xmlrpc.php
/api/search
/api/login
/product-search

For example:

GET /search?q=test
GET /search?q=test
GET /search?q=test
GET /search?q=test

repeated thousands of times.

This can indicate an application-layer HTTP flood.

8. Traffic Comes From Suspicious IP Patterns

Investigate whether traffic is heavily concentrated around:

• one IP
• related IP ranges
• particular autonomous systems
• hosting providers
• unusual networks
• unexpected geographic regions

However, blocking individual IP addresses is often ineffective against a genuinely distributed attack because traffic can originate from thousands or millions of devices.

9. Traffic Suddenly Comes From Unexpected Countries

Imagine a business normally receives traffic primarily from:

India
United States
United Kingdom
Canada
Australia

and suddenly enormous traffic appears from dozens of unexpected regions.

This may deserve investigation.

But geography alone should not determine whether traffic is malicious.

Global businesses, VPN users, search engines, mobile networks, and legitimate international visitors can create unusual geographical patterns.

10. User-Agent Patterns Become Abnormal

Analyze browser/user-agent information.

For example, enormous numbers of requests may share:

identical User-Agent
missing User-Agent
unusual User-Agent
automated HTTP client signatures

A combination of IP reputation, request behavior, headers, cookies, TLS characteristics, rate patterns, and application behavior generally produces better results than simply blocking one User-Agent string.

11. Your Firewall or Load Balancer Starts Exhausting Resources

A DDoS attack may overwhelm infrastructure before requests reach the web application.

Monitor:

Firewall CPU
Firewall memory
Connection table
NAT table
SYN rate
Packets per second
Load balancer connections
Dropped packets

If the connection table is full, legitimate users may be unable to establish new sessions.

12. Your CDN or Security Provider Generates DDoS Alerts

Modern DDoS protection platforms can detect attacks automatically.

For example, Cloudflare supports alerts containing information such as attack detection/mitigation time, attack type, maximum attack rate, target and the protection rule involved.

Such telemetry is usually much stronger evidence than simply noticing that the website feels slow.

DDoS Attack or Legitimate Traffic Spike?

This distinction is extremely important.

Suppose your website normally has:

1,000 visitors/day

but a television program mentions your company and suddenly:

50,000 visitors

arrive.

That may be a flash crowd, not a DDoS attack.

Compare characteristics such as:

Indicator	Legitimate Traffic Spike	Possible DDoS
User behavior	Normal browsing	Repetitive/abnormal
Pages requested	Multiple useful pages	Often concentrated
Session behavior	Normal	Frequently abnormal
Conversion/activity	May increase	Usually little business value
Request rate	Increased	Potentially extreme
Traffic pattern	Business-related	May lack explanation
Infrastructure load	Increased	Often excessive
Security alerts	Usually none	May trigger mitigation

Automated protection is valuable because distinguishing legitimate customers from attack traffic is one of the fundamental challenges of DDoS mitigation.

What Should a Business Do During a DDoS Attack?

Once an attack is suspected or confirmed, the objective should be:

Maintain service availability while filtering malicious traffic without unnecessarily blocking legitimate customers.

CISA recommends identifying the attack through monitoring, activating the organization's incident-response plan, and working with network/security and DDoS protection providers.

Step 1: Confirm the Incident

Check multiple sources:

• CDN dashboard
• hosting dashboard
• firewall
• router
• load balancer
• web-server access logs
• error logs
• bandwidth graphs
• CPU and memory monitoring
• database monitoring
• DNS monitoring
• external uptime monitoring

Try to determine whether the problem is:

Server failure
Application problem
Database overload
Network outage
DNS problem
Hosting outage
Legitimate traffic spike
DDoS attack

Avoid making major emergency configuration changes based on a single graph.

Step 2: Activate the Incident-Response Plan

Businesses should have a predefined DDoS response procedure.

Notify appropriate personnel such as:

IT Administrator
Network Administrator
Security Team/SOC
Hosting Provider
ISP
CDN/DDoS Provider
Application Team
Management
Customer Support

For a major incident, clearly assign responsibility.

For example:

Incident Commander
Network Lead
Application Lead
Security Lead
Communications Lead

This prevents multiple administrators from making conflicting changes during an emergency.

Step 3: Contact Your Hosting Provider or ISP

If the attack is saturating your Internet connection, changing rules on the local web server may achieve very little.

Why?

Consider:

Internet connection capacity = 1 Gbps
Incoming attack             = 5 Gbps

Your 1-Gbps connection can already be overwhelmed before your server gets an opportunity to filter the traffic.

In this situation, mitigation must occur upstream.

Contact your:

• hosting provider
• data-center provider
• ISP
• CDN provider
• DDoS mitigation provider

They may be able to filter or reroute attack traffic before it reaches your infrastructure.

Step 4: Enable or Tighten DDoS Protection

If the website is behind a capable CDN or DDoS mitigation platform, verify that protection is operating correctly.

Depending on the platform and attack, controls may include:

Managed DDoS protection
WAF rules
Rate limiting
Bot management
Browser challenges
IP reputation filtering
Request validation
Caching
Traffic anomaly detection

Avoid blindly activating extremely restrictive rules.

Aggressive emergency rules can stop legitimate customers along with attackers.

Step 5: Apply Rate Limiting

Rate limiting controls how frequently a client can access selected resources.

For example:

/login
/search
/api/login
/api/search
/password-reset

may need stricter request limits than ordinary static content.

Conceptually:

Normal visitor:
10 requests/minute → Allow

Suspicious automated client:
1,000 requests/minute → Rate-limit/challenge/block

The exact thresholds must be based on legitimate application behavior.

Step 6: Protect Expensive Application Endpoints

Not all URLs cost the server the same amount of resources.

For example:

/logo.png

may be inexpensive.

But:

/search?query=...

might trigger:

Web server
     ↓
Application
     ↓
Database
     ↓
Search operation
     ↓
Template generation

An attacker may intentionally target computationally expensive endpoints.

During an incident, administrators may temporarily:

• disable unnecessary search functions
• restrict expensive APIs
• increase caching
• limit unauthenticated requests
• simplify dynamic pages
• protect login endpoints
• disable unnecessary plugins/features

Step 7: Increase Caching

Caching reduces the number of requests that must reach the origin server.

Without caching:

Visitor
   ↓
Web Server
   ↓
PHP/Application
   ↓
Database

With edge caching:

Visitor
   ↓
CDN Cache
   ↓
Response

AWS similarly recommends CDN caching as part of reducing requests reaching an origin during DDoS conditions.

Static resources are especially suitable:

Images
CSS
JavaScript
Fonts
Downloads
Static HTML

Dynamic content can sometimes also be selectively cached.

Step 8: Protect the Origin Server

A common architectural mistake is placing a website behind a CDN while leaving the origin server's public IP directly accessible.

An attacker who discovers the origin IP may bypass the CDN:

Attacker
   ↓
Origin IP
   ↓
Web Server

instead of:

Visitor
   ↓
CDN / DDoS Protection
   ↓
Origin

Where technically appropriate, configure the origin so web traffic is accepted only through trusted reverse-proxy/CDN infrastructure.

AWS likewise recommends reducing the attack surface and restricting access to origin resources in DDoS-resilient architectures.

Step 9: Avoid Depending Only on Manual IP Blocking

An administrator may see malicious addresses and begin blocking them:

203.x.x.x
185.x.x.x
45.x.x.x
...

This can help with small abusive sources.

It is generally not a scalable solution for a distributed attack.

The attack may involve:

1,000 IPs
10,000 IPs
100,000 IPs

and addresses can continuously change.

Automated mitigation, reputation analysis, behavioral controls, rate limiting, WAF policies, and upstream filtering are generally more effective.

Step 10: Do Not Restart Servers Repeatedly Without Understanding the Cause

Repeatedly restarting:

Apache
Nginx
IIS
PHP-FPM
MySQL
Windows Server
Linux Server
Firewall
Router

may provide temporary relief but usually does not eliminate an ongoing external DDoS attack.

After the server returns:

Attack traffic → server → overload again

Restart services only when operationally necessary and after considering the effect on evidence, logs, customer sessions, and recovery.

Step 11: Preserve Logs and Evidence

Do not immediately delete logs.

Preserve:

Web access logs
Firewall logs
WAF logs
CDN analytics
Load-balancer logs
Network-flow data
System logs
Application logs
Security alerts

Also record:

Attack start time
Attack end time
Peak bandwidth
Peak requests/second
Peak packets/second
Target IP/domain
Target URL
Protocols
Countries
Source networks
Mitigation actions
Service impact

This information is useful for incident analysis and improving future protection.

Step 12: Monitor False Positives

One danger during emergency mitigation is accidentally blocking real customers.

Watch:

HTTP error rates
Successful sessions
Checkout/login success
API success rates
Support complaints
Geographical availability
WAF blocks
Challenge rates

If a new security rule suddenly blocks thousands of legitimate requests, adjust it carefully.

DDoS controls should ideally be baselined and tuned before an incident. AWS recommends enabling protection during normal periods so systems can establish traffic patterns and monitoring relevant metrics regularly.

Step 13: Communicate With Customers

For a significant outage, customer communication should be concise.

For example:

We are currently experiencing abnormal network traffic affecting access to our online services. Our technical team and service providers are working to restore normal availability.

Avoid publicly disclosing unnecessary technical details while mitigation is underway.

Maintain alternative communication channels if your primary website or VoIP infrastructure is unavailable.

Step 14: Continue Monitoring After Traffic Returns to Normal

Do not assume the incident has ended simply because the website becomes available again.

Attackers may:

Attack
↓
Stop
↓
Wait
↓
Attack again

Continue monitoring traffic and infrastructure for recurrence.

What Businesses Should NOT Do During a DDoS Attack

Avoid these common mistakes:

Do not assume every traffic spike is an attack.

Confirm using multiple indicators.

Do not rely entirely on manual IP blocking.

Distributed attacks can involve huge numbers of sources.

Do not expose the origin unnecessarily.

Attackers may bypass CDN protection.

Do not make uncontrolled firewall changes.

Emergency rules can cause self-inflicted outages.

Do not delete logs.

They may be essential for investigation.

Do not wait until an attack to develop your response plan.

Preparation substantially reduces response time.

Do not assume increasing server RAM or CPU alone solves DDoS.

Additional capacity can help absorb some load but cannot compensate for an attack that saturates upstream bandwidth or network infrastructure.

Recommended DDoS Monitoring Architecture

A well-protected public website can conceptually use:

                    Internet
                       │
                       ▼
              DDoS Protection / CDN
                       │
                       ▼
                      WAF
                       │
                       ▼
                 Load Balancer
                       │
               ┌───────┴───────┐
               ▼               ▼
          Web Server 1     Web Server 2
               │               │
               └───────┬───────┘
                       ▼
                    Database

Security monitoring should collect telemetry from each relevant layer.

AWS guidance similarly emphasizes edge protection, scalable services, traffic filtering, monitoring, and having a DDoS response plan.

Important Metrics Businesses Should Monitor

At minimum, monitor:

Requests per second
Connections per second
Concurrent connections
Bandwidth
Packets per second
CPU utilization
Memory utilization
Disk I/O
Network errors
Dropped packets
HTTP 4xx responses
HTTP 5xx responses
Application response time
Database connections
Database CPU
Cache hit ratio
WAF blocks
CDN requests
Origin requests
DNS health

More importantly, establish normal baselines for these metrics.

If normal Monday traffic is:

RPS:       100
Bandwidth: 20 Mbps
CPU:       30%

and suddenly becomes:

RPS:       15,000
Bandwidth: 700 Mbps
CPU:       100%

without a legitimate business explanation, investigation should begin immediately.

Create Automatic Alerts

Do not depend on someone manually noticing the website is down.

Configure alerts for conditions such as:

Website unavailable
Response time > threshold
Bandwidth > threshold
RPS > threshold
CPU > threshold
HTTP 5xx > threshold
WAF blocks > threshold
Connection count > threshold

Where available, enable your DDoS provider's attack notifications as well.

Prepare a DDoS Incident Runbook Before an Attack

Every organization operating an important public service should maintain a DDoS response runbook.

It should contain:

Hosting provider contact
ISP emergency contact
CDN/DDoS provider contact
Domain/DNS provider details
Cloud provider support process
Internal IT contacts
Security contacts
Management escalation contacts
Application owners
Communication procedure
Emergency configuration procedure
Recovery procedure

AWS explicitly recommends creating a DDoS response plan/runbook in advance.

Example DDoS Investigation Workflow

When a website suddenly becomes unavailable:

Website Slow/Offline
        │
        ▼
Check External Monitoring
        │
        ▼

        ▼
Check Bandwidth / PPS / RPS
        │
        ▼

Post-Incident Review

After the DDoS Attack: Conduct a Post-Incident Review

Once the attack has ended, investigate:

1. How large was the attack?

Record:

Peak Mbps/Gbps
Peak packets per second
Peak requests per second
Duration

2. What was targeted?

Determine whether the attacker targeted:

Website
IP address
DNS
API
Login page
Search function
Firewall
Load balancer

3. Which control failed?

Was the problem:

Insufficient bandwidth?
No CDN?
Origin IP exposed?
Missing rate limiting?
Application bottleneck?
Firewall exhaustion?
Database exhaustion?
DNS vulnerability?

4. How long was the outage?

Calculate:

Attack duration
Detection time
Response time
Mitigation time
Recovery time

5. What should change?

Possible improvements include:

DDoS protection
CDN
WAF
Rate limiting
Better caching
Origin protection
Additional capacity
Load balancing
Improved monitoring
Automated alerts
Incident runbook
Provider escalation procedures

Frequently Asked Questions (FAQ)

1. How can I tell whether my website is under a DDoS attack?

Look for several correlated indicators: unexplained traffic spikes, high bandwidth, abnormal requests per second, unusual connection counts, high latency, server-resource exhaustion, repeated requests to particular URLs, unexpected traffic patterns, and alerts from your hosting/CDN/DDoS provider.

A slow website alone does not prove a DDoS attack.

2. Can a sudden increase in traffic always be considered DDoS?

No.

A viral article, advertising campaign, product launch, software update, or legitimate business event can create a large traffic spike.

Compare traffic with historical baselines and analyze visitor behavior before classifying the incident.

3. Can Google Analytics detect a DDoS attack?

Analytics platforms can sometimes reveal unusual visitor patterns, but they should not be your primary DDoS detection mechanism.

Use network, CDN, WAF, firewall, load-balancer, hosting, and server telemetry.

4. Can server logs identify a DDoS attack?

They can be extremely useful for application-layer attacks.

However, some network-level attacks may overwhelm upstream infrastructure before meaningful requests ever reach the web server.

Therefore, combine server logs with network and provider telemetry.

5. What should I do first during a DDoS attack?

Confirm the incident using multiple monitoring sources, activate your incident-response procedure, and contact the relevant hosting, ISP, cloud, CDN, or DDoS mitigation provider when appropriate.

6. Should I block attacking IP addresses?

Blocking individual addresses may help with limited abusive traffic, but large DDoS attacks can originate from huge numbers of distributed sources.

Use scalable automated mitigation rather than depending solely on manual blocking.

7. Can a firewall stop a DDoS attack?

A firewall can help with certain attacks, but it cannot guarantee DDoS protection.

A sufficiently large attack may saturate the Internet connection before traffic reaches the firewall, and the firewall itself can become a resource-exhaustion target.

8. Can a CDN help during a DDoS attack?

Yes. A properly configured CDN can absorb and distribute traffic, cache content, reduce origin requests, and—in platforms offering integrated DDoS protection—filter malicious traffic at the provider's edge.

9. What is rate limiting?

Rate limiting restricts the number of requests permitted from a client or according to another defined traffic characteristic during a specified period.

It is especially useful for protecting login pages, APIs, search functions, and expensive dynamic endpoints.

10. Why is hiding or restricting the origin IP important?

If attackers know the origin server's public IP, they may attempt to bypass CDN or reverse-proxy protection and send traffic directly to the server.

Origin access should therefore be restricted where the architecture and provider support it.

11. Should I restart my web server during a DDoS attack?

Only when operationally necessary.

Restarting a server does not stop incoming malicious traffic. If the attack continues, the server may simply become overloaded again.

12. Should businesses increase server resources during an attack?

Additional capacity can sometimes help absorb application demand, but scaling alone is not a complete DDoS strategy.

A sufficiently large volumetric attack can exceed network capacity regardless of server CPU or RAM.

13. Can small websites be targeted by DDoS attacks?

Yes.

DDoS attacks can target organizations of any size, including small businesses, e-commerce sites, forums, APIs, SaaS applications, hosting customers, and individual servers.

14. Can WordPress websites experience DDoS attacks?

Yes.

WordPress websites can be targeted with HTTP floods against dynamic resources such as login, search, XML-RPC, API, or other application endpoints. Appropriate CDN, WAF, caching, rate limiting, plugin security, and server hardening can reduce risk.

15. How long can a DDoS attack last?

There is no fixed duration.

An attack can occur as a short burst, continue for an extended period, or repeatedly stop and restart. Monitoring should therefore continue after apparent recovery.

16. Does a DDoS attack mean my website has been hacked?

Not necessarily.

DDoS primarily targets availability. It does not automatically mean the attacker has compromised the server or stolen information.

However, businesses should still investigate other suspicious activity because availability attacks can occur alongside other security incidents.

17. Can DDoS attacks target APIs?

Yes.

Attackers can flood APIs with requests, particularly endpoints that require expensive database queries or computational processing.

API gateways, authentication, caching, request validation, WAF controls, and rate limiting can help.

18. How can businesses prepare before a DDoS attack occurs?

Implement layered protection before an incident:

CDN
DDoS mitigation
WAF
Rate limiting
Caching
Load balancing
Origin protection
Monitoring
Automated alerts
Incident-response plan
Provider escalation contacts
Regular configuration reviews

DDoS protection is considerably easier to deploy and tune during normal operation than during a major outage.

Conclusion

Detecting a DDoS attack requires more than noticing that a website is slow.

Businesses should monitor requests per second, packets per second, bandwidth, connection rates, HTTP errors, server resources, CDN/WAF events, application behavior, and traffic patterns and compare those metrics with established normal baselines.

When an attack occurs, the business should quickly confirm the incident, activate its response plan, engage hosting/ISP/CDN/DDoS providers, protect the origin, apply appropriate rate limits and WAF controls, increase caching where possible, preserve logs, monitor false positives, and maintain customer communication.

Most importantly, DDoS defense should be implemented before an attack occurs. Always-on protection, good architecture, monitoring, automatic alerts, capacity planning, and a tested incident-response runbook can turn a potentially prolonged outage into a manageable security event.
