Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 6 o1 e9 S2 e/ ]% C! w" Z! B) j
; P& h" d- j4 @0 H" l+ n9 uThe 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 N" h# W+ Q# ~0 z2 J1 f2 \, s+ m( i, ~- f, y) k
We’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. ) f( J6 y9 y; D( I* R/ Q2 P9 ^( C 8 e7 c/ e1 @( R~The Cloudflare Team * G) v H% ~) _.
