这种全球性的502 应该不是ddos 引起的1 W( u; E) T2 w: F- j1 f

Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 5 j' {9 E! o, S; S' E) {
: b' n) o8 @0 ?/ s0 z. N
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. ; S! Y+ t% X8 A3 p/ j) n
