( D$ D# O9 D) L5 |1 f7 O
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.

$ F7 A& }3 W; J" h* tWe’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.
