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. l& V+ e1 F T1 o7 ]! u# v2 l) m0 @. w: D& R8 ]5 r
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. - ^3 x1 u0 V% i e" R R1 s
