Dear Cloudflare Customer,

Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes.

  A- T9 W: S" ^1 }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.
