Keypoints

- The root cause was a routine database permissions update that caused the Bot Management system to generate an oversized configuration file.
- The oversized file exceeded size limits, crashing the core traffic processing system and causing 5xx errors.
- Cloudflare’s engineers quickly identified the issue and restored normal operations by replacing the faulty file.
- This incident marks Cloudflare’s most significant outage since 2019, impacting core CDN and security services.
