### Cloudflare Outage Briefly Knocks Internet’s Top Sites Offline
An intermittent outage at Cloudflare on Tuesday briefly knocked many of the Internet’s top destinations offline. Some affected Cloudflare customers were able to pivot away from the platform temporarily so that visitors could still access their websites. However, security experts warn this may have triggered an impromptu network penetration test for organizations relying heavily on Cloudflare to block abusive and malicious traffic.
---
### Timeline and Impact of the Outage
- Time of Incident: Around 6:30 EST / 11:30 UTC on Nov. 18
- Initial Issue: Cloudflare’s status page reported an “internal service degradation.”
- Duration: Several hours with services coming back up and failing again intermittently.
- Customer Challenges:
- Many websites could not migrate away from Cloudflare because the portal was unreachable.
- Some also relied on Cloudflare for DNS services.
- Despite this, some customers managed to pivot their domains away during the outage.
---
### Security Implications of the Outage
Aaron Turner, faculty member at IANS Research, commented on the security risks during the outage:
- Cloudflare’s Web Application Firewall (WAF) effectively filters out top application-layer attacks such as:
- Credential stuffing
- Cross-site scripting (XSS)
- SQL injection
- Bot attacks
- API abuse
- Opportunity for Organizations:
- To analyze their WAF logs and understand how their app and website defenses performed without Cloudflare’s protection.
- Turner noted that developers might have relied too much on Cloudflare’s edge filtering, potentially neglecting internal security QA.
- Example:
- One company saw a huge increase in log volume and is still distinguishing between legitimate malicious traffic and noise.
- Risks During the Outage:
- About an eight-hour window where several high-profile sites bypassed Cloudflare for availability.
- Organizations relying on Cloudflare for OWASP Top Ten vulnerabilities and bot blocking need to closely inspect exposed infrastructure for persistent threats.
- Cybercrime Concerns:
- Attackers may have noticed targets dropping Cloudflare and launched new attacks during that window.

| Here is a detailed threat assessment based on the article describing the Cloudflare intermittent outage on November 18:
---
### Overview:
The Cloudflare outage caused a significant disruption for many websites relying on its services, including DNS and web application firewall (WAF) protections. The outage lasted several hours and led some organizations to temporarily bypass Cloudflare, exposing them to increased risk from malicious traffic and attacks previously mitigated by Cloudflare’s security controls.
---
### Threat Vectors and Risks:
1. Increased Exposure to Application-Layer Attacks:
- Cloudflare’s WAF protects against top OWASP vulnerabilities such as SQL injection, cross-site scripting (XSS), credential stuffing, bot attacks, and API abuse.
- When organizations bypassed Cloudflare, these protections were temporarily removed, potentially allowing attackers to exploit vulnerabilities that had been previously mitigated.
- Developers might have been complacent, relying on Cloudflare as the primary defense, thus leaving application code less secure.
2. Potential for Persistent Compromise:
- The outage created an 8-hour window where attackers could have launched attacks without the usual Cloudflare protections.
- Any successful intrusions during this period could lead to persistent access or backdoors that remain even after switching back to Cloudflare.
- Organizations need to conduct thorough log reviews and forensic analysis to detect and remediate any such persistence.
3. Exploitation of DNS Changes and Routing Adjustments:
- Attackers monitoring DNS changes could identify when organizations removed Cloudflare protections.
- This visibility allows threat actors to time attacks precisely when defenses are lowered.
- Emergency DNS or routing changes made during the outage might have been insufficiently controlled or documented, increasing risk.
4. Shadow IT and Emergency Workarounds:
- The outage forced some employees to use personal devices, home networks, or unsanctioned SaaS tools to maintain business continuity.
- This behavior increases the attack surface through unmonitored or less secure endpoints and services.
- Temporary tunnels, vendor accounts, or services stood up during the outage may remain active, creating ongoing security risks.
5. Single Point of Failure and Vendor Dependency:
- Cloudflare services are used by an estimated 20% of websites, making it a critical infrastructure provider.
- Heavy reliance on a single cloud provider or DNS/WAF vendor creates systemic risk.
- Outages at Cloudflare or other major providers like AWS or Azure can cascade and impact many organizations simultaneously.
