I noticed that Quad 9 is not able to respond to the spy.pet query:

$ dig spy.pet @9.9.9.9 +short
;; communications error to 9.9.9.9#53: timed out

But Cloudflare DNS is able to do it:

$ dig spy.pet @1.1.1.1 +short
104.26.0.165
104.26.1.165
172.67.74.73

And to be sure, I checked another domain with the same TLD to rule out the option that Quad9 is unable to handle the .pet TLD, but I received a correct answer…

$ dig hello.pet @9.9.9.9 +short
3.64.163.50

Does Quad9 censor DNS queries?

    You are using, this option (9.9.9.9):

    Recommended: Malware Blocking, DNSSEC Validation (this is the most typical configuration)

    You can disable it, by setting the 9.9.9.10 IP:

    Unsecured: No Malware blocking, no DNSSEC validation (for experts only!)

        Because that’s their thing. That’s the first thing that’s right in your face when you open their website. It’s like asking why AdGuard or even PiHole block DNS results.
