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

Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 9 U, W- t, P; y. j2 k( d
: W1 E- |5 R. G V1 SThe 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.
