[Cloudflare Outage Caused by Configuration Error, Not Cyberattack] An analysis report released by Cloudflare shows that the large-scale outage on November 18 was caused by an erroneous configuration file generated after database permission adjustments, leading to anomalies in the core proxy system. This impacted multiple products, including CDN, security services, Workers KV, Turnstile, and Access. The team initially misjudged the issue as a DDoS attack but eventually resolved it by rolling back to the previous configuration file. All services were restored to normal at 01:06 AM (UTC+8) on November 19. Cloudflare stated that it will accelerate system resilience upgrades to prevent similar incidents in the future.
