Cloudflare Down Today: Global Internet Outage on December 5, 2025 – What Happened, Who Was Hit, and If It’s Fixed Now
Cloudflare suffered a major outage on December 5, 2025, starting just before 09:00 UTC, disrupting up to 20% of websites and causing 500 Internal Server Errors on platforms like Zoom, LinkedIn, and Spotify. The disruption lasted about 30–40 minutes. Cloudflare traced the cause to a Web Application Firewall update, not a cyberattack. Most services recovered after 09:12 UTC, though some issues remain under review.
