I host multiple sites and services that work without issues.
1 of them went down today and won't come up. It was very odd that only 1 went down.

It turns out, it's the only one using Cloudflare.

I can't login to Cloudflare console.
I can't even login to my registrar to disable Cloudflare (dns config), because they also use Cloudflare!

My hands are tied on this. We all wait for Cloudflare to fix this, and I can't think of a way to fix this on my side.

This is peak centralization. Registrars using Cloudflare can bring the internet to a deadlock.
