Dear Cloudflare Customer, * X6 c4 Y) Z5 N) P h! d2 [4 f+ f# CToday at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes. 5 C6 i) `" R+ G! C& Y% g
; H2 O ^# O) T! f6 K- tThe 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. 6 ~' W4 ~3 S. Z8 K9 e8 y
