Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 7 x' [" m' l& k( N4 @+ M, H. K
$ |4 {6 v* W3 F. o) m7 ]% t( B* ^+ pThe 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. 9 c/ D0 A4 x1 S* k! l2 F$ W4 W: a- N& {1 @
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. % n! l0 m: O# q' f1 [% E: [
