- Cloudflare outage disrupted major websites and crypto platforms for 25 minutes.
- Issue caused by internal config changes, not a cyberattack, affecting 28% of HTTP traffic.
- Incident underscores risks of centralized internet infrastructure for online services and crypto.
Internet infrastructure provider Cloudflare experienced a network outage on Friday, temporarily disrupting dozens of websites and cryptocurrency platforms.
The incident lasted about 25 minutes and affected roughly 28% of HTTP traffic across the network. According to Cloudflare, the outage stemmed from internal configuration changes during the deployment of a security update, not from a cyberattack. Notably, services were fully restored after the company reverted the changes.
Impact on Websites and Crypto Platforms
The outage affected several popular websites, including X, Substack, Canva, and DownDetector. Centralized crypto exchanges such as Coinbase and Kraken also became temporarily unavailable.

Similarly, platforms like Jupiter, Raydium, and Meteora also went offline. Users of DeFi protocols also reported interface interruptions. The incident demonstrated how dependent major online services and crypto platforms are on a single provider, emphasizing the risks of centralized network reliance.
Technical Cause
The outage occurred during a rollout addressing a vulnerability in React Server Components (CVE-2025-55182). Cloudflare increased its HTTP request buffer from 128KB to 1MB, but a subsequent change disabled an internal Web Application Firewall testing tool.
On older FL1 proxy servers, this triggered a Lua runtime error, causing HTTP 500 responses. Notably, newer FL2 proxies and servers in China were unaffected. No cyberattack was involved. The error stemmed from longstanding code not previously triggered.
Response and Future Mitigation
Cloudflare reverted the configuration at 09:12 UTC, restoring full service. The company plans to:
- Improve deployment processes with gradual rollouts and validation checks.
- Enhance critical operation handling to maintain service during failures.
- Update error-handling logic to default to safe traffic handling.
A full resiliency report is expected next week. This follows a similar outage on November 18, 2025, underscoring the vulnerabilities of centralized infrastructure.

Historical Context: Web3 as an Alternative
A major AWS outage on October 20 disrupted services across the U.S. and Europe, affecting apps like Snapchat, Fortnite, and Alexa. Both incidents illustrate how centralized providers can create single points of failure, amplified by interconnected dependencies.
However, decentralized networks like Filecoin, Arweave, and Akash distribute computing and storage across independent nodes, reducing single points of failure. While facing scalability and speed challenges, Web3 offers greater resilience, transparency, and security compared to centralized systems.
