Seems to be a lot of stuff flapping right now. I was able to load a client site that was behind Cloudflare, and now not.

cloudflare.com was returning Connection Refused, then error 522 cloudflarestatus.com was returning Connection Refused, now can't even resolve the IP

My guess would be that a router misconfiguration is being progressively deployed throughout their infrastructure.

EDIT: Continues to look like a cascading failure across their network. 1.1.1.1 is now unreachable for me.
