Nearly a month after Amazon Web Services went down, Cloudflare, which offers a Content Delivery Network (CDN) to caching content from web servers so such content can load quickly to users globally and DNS hosting services among other things, also experiences a disruption to its service on November 18 2025. Cloudflare’s disruption resulted in several websites and services such as X (formerly Twitter), ChatGPT, Uber, Canva and not being accessible for a few hours.

The disruption to Cloudflare was not due to an external attack but due to a misconfiguration to a database resulting in a larger file generated which disrupted traffic being delivered on Cloudflare’s network.

Cloudflare has posted a detailed blog post on what went wrong less than 24 hours after the incident.
