Cloudflare’s global infrastructure suffered a significant disruption on November 18, 2025, due to an unexpected spike in traffic, leading to HTTP errors on several major platforms, including X, ChatGPT, and Canva. This interruption started around 12:00 UTC and affected millions of users worldwide. Cloudflare responded by temporarily disabling some of its access points, including WARP in London. Despite the restoration of some services, the cause of the traffic surge remains under investigation. The outage serves as a reminder of the critical role Cloudflare plays in internet infrastructure.
