Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. ) u3 J% F! N6 T# i0 N0 K- T+ 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. % `( F% h m, w8 T1 T, k A3 h3 m
5 n* C/ m: P: MWe’re deeply sorry about how this disruption has impacted your services. Our engineering teams continue to investigate this issue and we will be sharing detailed incident report(s) on the Cloudflare blog. 9 r! k$ O; {' ] l o! C% Q0 d* Q, x& k8 \6 B7 f3 q
