Dear Cloudflare Customer,

9 z# y( b r( N0 t, r" J+ GToday at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes.
e! ?0 e7 k: z
' a8 q* K6 r+ G; X! {% GThe 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.
