Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 7 R* C/ y7 |! N2 j' k ) r1 j8 P3 ?; _ l6 t4 k: M# WThe issue was triggered by a bug in a software deploy of the Cloudflare Web Application Firewall (WAF) which resulted in a CPU usage spike globally, and 502 errors for our customers. To restore global traffic we temporarily disabled certain WAF capabilities, removed the underlying software bug, then verified and re-enabled all WAF services. 5 e. a1 [3 @- r/ r$ M) n
