Cloudflare: Massive outage caused by misconfiguration, not a cyberattack.

According to an analysis report released on the Cloudflare official blog, the massive outage that occurred on November 18 was not caused by an external network attack, but rather by an incorrect configuration file generated after a database permission adjustment, which caused an anomaly in the core proxy system and triggered outages in multiple products, including CDN, security services, Workers KV, Turnstile, and Access. This is the most serious incident since 2019.

The report indicates that the team initially misjudged the incident as a DDoS attack, but ultimately resolved it by rolling back the old configuration files. All related services were fully restored at 01:06 AM Beijing time on November 19th. Cloudflare stated that the outage was "unacceptable" and will accelerate efforts to improve system resilience.
