Dear Cloudflare Customer, V( v0 f' a, s

) M4 _3 q) z. u# P- n9 c
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. , f0 M+ k3 j: Q, ]
