Yeah. They seem to work for me, too. There was a few weeks where one of my devices got trapped in the loop gp described and it was very frustrating. I am not using Cloudflare DNS.
There is a feud between CloudFlare and the person/people running Archive.is/ph, where they blame each other for X, and people using CloudFlare's DNS gets sent into some redirect loop or something when they try to access the website.
