Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. $ g, ^/ i9 s8 I. n) @. l% ?
8 G* p: F5 t( f9 m0 L: HThe 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. # V# u! B6 M8 ?7 g8 W$ ~3 j
