Dear Cloudflare Customer, - S+ r. ~! t8 k" H Z
`# l, o5 z/ X5 ^9 P3 rToday at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes.
% d% o, N, W$ `7 \/ B X _# M% e/ ^- v# }
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. 3 N7 ~6 E- ~1 I. g
