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

Dear Cloudflare Customer, $ a- V( r3 D, Y- H$ g2 Q- C
4 l( w0 X3 x# \Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes.
* V- C) m8 X0 d. e
% I1 Y5 f* I- cThe 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.
