这种全球性的502 应该不是ddos 引起的

Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. - \% S, C8 Z5 c
$ X) U; _8 s1 t9 Y. t4 R p6 l6 k
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.
