DNS Speed Test

I use Quad9 (the winner in this benchmark for me, personally) as a fallback resolver, in case the one I operate and use primarily (https://resolv.us.to) happens to break. I created my own (very simple - there's no global unicast with geolocation involved or anything!) service and made it publicly available a few years back because I think it's important not to have too few alternatives for DNS resolution to choose from as an "ordinary" Internet user, since meddling with DNS, down to individual ISPs' servers, is one of the cornerstones of Internet censorship, which I believe must be opposed whenever possible.

Naive question: can pi-hole build something like a pro-active cache based on frequently visited domains? Would that make sense?

I’m currently with nextDNS, which is doing quote well in this test, both on my home internet as well as my iPads 5G.

In both tests though, I notice Quad9 is faster. So I looked them up, and they seem to be a very interesting alternative to NextDNS.

Thanks for helping me find this new service.
