Dear Cloudflare Customer, 8 |' m& s: D6 i M0 i5 l- P7 w) j 3 G6 z- {9 l7 \5 k3 m k8 b2 JToday at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. " w6 I6 N2 u$ R7 ~; f' i; w/ m* o% I% U
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. $ M) x& Y4 V I$ b& h # Z: C" s7 l3 eWe’re deeply sorry about how this disruption has impacted your services. Our engineering teams continue to investigate this issue and we will be sharing detailed incident report(s) on the Cloudflare blog. 2 \2 f6 Y+ Q5 j: ]- z' d7 l
