Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 7 }9 m" F @! b, o8 D0 p) b0 ^ p9 ?! e: O& o
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. / Q0 S6 U) A1 P' Y 2 n; H+ H9 D- c" w1 N8 o0 e. n6 D3 qWe’re deeply sorry about how this disruption has impacted your services.
