I’m sorry you feel that way, but you literally started off by doing that.

This seems like a lot of text for saying “unless you can predict all the specific ways a bad thing could happen, I think putting all your eggs in one basket is fine.” And under some circumstances you’d be right.

I wouldn’t buy domains from Cloudflare from a risk mitigation perspective. At work I direct six figures of budget their way annually, but as a free-tier customer in my personal life I don’t trust them not to fuck up at some point and lock my account. If I register my domain elsewhere I can bring myself back online by moving the nameservers. If it’s registered at Cloudflare I’m fucked.
