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: R7 ]4 J+ b4 K

Dear Cloudflare Customer, * r; S' b# I. [' g; Q) s! V

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. 7 x0 G2 m' K. _& N; `
