Dear Cloudflare Customer, ; R* `0 B8 t; Q: g/ K

1 d$ T2 C: k/ _% X' jThe 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.
