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.

https://downdetectorsdowndetectorsdowndetectorsdowndetector.... reports that https://downdetectorsdowndetectorsdowndetector.com/ is down, guessing downdetectorsdowndetectorsdowndetector runs via cloudflare!

No idea why the media always relies on/cites this useless site...

You know what, maybe AI is taking all the goddamn jobs

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...

Time to use some local ai with Docker Model Runner :)

No cloudflare no problem

I assume this is why Claude stopped working

There are other LLMs you can ask to be absolutely, 100% sure.

The entirety of shopify was down too for 30 minutes.

Appears to be fixed now. Just lost 30 minutes of working.

If this is unwrap() again, we need to have a talk about Rust panic safety.

jasmes

Time to rewrite Rust’s unwrap() in Rust obviously.

Now multiply that 'just' by the number of people affected.
