Service Impact Notification — Cloudflare Outage and OneFirewall Services
We are writing to update on the service impact caused by today’s outage at Cloudflare, Inc. (Cloudflare). OneFirewall’s platform leverages Cloudflare as a CDN and edge-delivery layer for various public-facing components, and this outage temporarily affected some services.Background of the Outage
On Tuesday, 18 November 2025, Cloudflare experienced a global service incident that disrupted access to several major platforms, including ChatGPT, X (formerly Twitter), Spotify, Canva, and others.Cloudflare reported that its network — which supports an estimated ~20% of the web — encountered an internal service degradation triggered by a very large configuration file or unexpected traffic spike affecting its traffic processing pipeline. Cloudflare also stated there is no evidence of malicious activity, and the root cause is still under review.
Impact on OneFirewall Services
Thanks to the resilience of our backend threat-intelligence infrastructure, all Core Threat Intelligence Services remained fully operational throughout the incident. However, because our public UI and API rely on Cloudflare’s CDN, customers experienced limited access during the outage.- Outage timeframe: [Circa 6hours from 7am UTC]
- During this window, customers were unable to receive new IoC feeds via the public API/UI.
- Once Cloudflare resolved the issue, all services auto-restored without any manual action required.
