Dear Cloudflare Customer, " f! C1 e U/ L$ G

' D- i( ?. _6 S- U: l( aThe 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.
