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. . T ~3 y( Y: o! z6 f/ A8 A' s& R8 Z8 C
We’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. + ^, t% d: y2 e L
