Cloudflare Outage Brings Down Major Websites for Hours

  • On Dec. 5, Cloudflare, the internet infrastructure company, experienced a global outage that disrupted many major websites for hours before implementing a fix.
  • Cloudflare said a firewall change to its Web Application Firewall parses requests impacted availability while addressing a security vulnerability in React Server Components following React's Dec. 3 update.
  • Downdetector logged surges in reports for multiple platforms including LinkedIn, Coinbase, Substack, Shopify, HSBC and Deliveroo a little after 9:00 a.m. London time.
  • This outage is the second in a month for Cloudflare, which emphasized it resulted from an internal change, not an attack; last month's error affected X, Google, OpenAI and United Press International.
  • Cloudflare's incident report shows its network includes distributed denial of service protections, and the company identified the issue and began investigating just before 4 a.m. EST on Dec. 5, 2025.
