Dear Cloudflare Customer,

Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes.
* _1 a2 W R3 P, ?7 c" l0 e/ n0 P/ J+ f7 e+ \7 {8 D! h
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.

# j- X: p4 [+ l5 x- x/ b2 e0 C$ yWe’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.
