昨晚 cloudflare 发生了全球502， 也就是说只要是使用了cloudflare 的站点全部502，是全球范围内的事情- d" ^# r* R1 x. D0 U7 X# C

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. : P1 f- _! V% r
