Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. - t* Y# R0 \8 h1 O
9 U& O# T! d; |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. 9 [$ `$ S+ \, V. y0 d - f8 V0 |( S& s: |/ E# T& T+ U2 hWe’re deeply sorry about how this disruption has impacted your services.
