On November 18, 2025, a major service outage occurred at Cloudflare, one of the world's largest CDN and security service providers. The outage began around 11:48 (UTC) and affected multiple services.

Numerous websites and applications using Cloudflare's services became unavailable or experienced display issues. Connection failures and errors were reported across various services, including X (Twitter).

On the restored X (Twitter), posts about the outage flooded in, with comments like "The internet is over" and "I tried to tweet that Twitter was down but Twitter was down."
Cloudflare has already identified the issue and restored major services after approximately 3 hours. The company announced that "a fix has been implemented and the incident has been resolved," and they are now conducting continuous monitoring.
