Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 8 I0 h1 ]7 c$ d7 V
2 S. m' |: [4 @. hThe 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. 8 u' z4 s7 Y. j! a; ~
