Cloudflare Down Again – and DownDetector Is Also Down

·December 5, 2025f311a
A change made to how Cloudflare's Web Application Firewall parses requests caused Cloudflare's network to be unavailable for several minutes this morning. This was not an attack; the change was deployed by our team to help mitigate the industry-wide vulnerability disclosed this week in React Server Components. We will share more information as we have it today.

They pretty much said this. All the big companies that had recent outages are companies that publicly embraced vibe coding.

And once again simple self hosted services remain up.

Neat trick: just do job interviews when Cloudflare is down...
