Cloudflare experienced a service outage on February 20, 2026, at 17:48 UTC. A subset of customers using its Bring Your Own IP service saw their routes to the Internet withdrawn via Border Gateway Protocol. The issue was not caused by a cyberattack or malicious activity. The outage was caused by a change Cloudflare made to how its network manages IP addresses onboarded through the BYOIP pipeline. The change caused the unintentional withdrawal of customer prefixes. This led to services and applications being unreachable from the Internet for affected customers. The website for Cloudflare's recursive DNS resolver at 1.1.1.1 saw 403 errors. The total duration of the incident was 6 hours and 7 minutes. Most of that time was spent restoring prefix configurations to their state prior to the change. Cloudflare engineers reverted the change after observing the failures. Approximately 1,100 BYOIP prefixes were withdrawn from the network. Some customers were able to restore their own service by using the Cloudflare dashboard to re-advertise their IP addresses. The company resolved the incident when it restored all prefix configurations. Cloudflare said it was sorry for the impact to its customers.
