On July 18, 2020 at 2:22AM UTC, a configuration error in Cloudflare's backbone network caused an outage lasting 27 minutes, affecting Internet properties and Cloudflare services. The issue was localized to certain geographies due to the architecture of their backbone. Traffic dropped by about 50% across their network. The problem occurred when a configuration update on a router in Atlanta caused all traffic across the backbone to be sent there, overwhelming the Atlanta router and causing Cloudflare network locations connected to the backbone to fail. No attack or breach was involved. Cloudflare has made changes to prevent this from happening again and apologized for the disruption.
