Yeah the mentioned capcha features of CloudFlare are a reverse proxy & caching CDN they provide; Quad9 is a DNS resolver only AFAIK.
Cloudflare also provides DNS resolving, but this isn’t something that a fediverse instance can put between itself and the user (that’s DNS hosting, which would probably be set up in connection with the aforementioned reverse proxy and CDN services)
Some folks are commenting here that they have had Quad9 issues with reliability; if true that’s a recent occurrence as I used them for years as a resolver without issue (been using my ISP as a DNS resolver for about 2 years now as I’ve moved and haven’t had the ability to set up my old servers in my new location. Soon, I hope!)
You need to be more descriptive, use in what regard? Both are capable DNS providers but as far as I’m aware, Cloudflare is also a domain registrar.
Also each instance of Lemmy is configured differently, perhaps Lemmy.zip uses cloudflare but that isn’t the case for every instance of Lemmy.
