Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. ! V% t" u( U: [; e# h5 f5 ]1 U% A
% m3 K4 G3 o; b8 W, O; |The 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. + P; Z- ?3 E s( Y' \$ F' _0 w
