I used them in the past (many years ago) and was very surprised when my DNS was affected by a cloudflare outage. Turns out (back then) they relied on the cf network for DoS protection against their resolvers[1]. I was surprised to learn that and honestly thought that if I already take a dependency on cloudflare I might as well have them host my zones directly for free.

[1] Not completely sure but I think this was the incident https://blog.dnsimple.com/2020/07/incident-dns-resolution/

At one point we were using Cloudflare's DNS Firewall product for our entire edge network. We have since moved half of our edge network to our own infrastructure and are currently in the process of expanding our edge network further, so at this point an outage at Cloudflare should be at least partially mitigated for our customers due to our separate edge network, and eventually it should be completely independent.
