It was Cloudflare's botched routing again. It even took down the Bitcoin Wiki and my website.
Hip Hip Hurray! I think I missed all the fun again 
I don't know why I have a feeling we are going to see more of this issues in future, but I think forum should have some alternative option ready in case Cloudflare explodes again.
If anyone knows good usable alternative for Cloudflare in 2022 please post it below.
