dig @1.1.1.3 archive.is

gives back 0.0.0.0

That's strange: 1.1.1.3 is CloudFlare's "no known porn / no known malware" resolver. Why does it filter out archive.is?

I'm usually fine with 1.1.1.3 and I do like that it's filtering out known porn and known malware sites.

    dig @1.1.1.1 archive.is

works fine though.
