however, i noticed archive.is has a CNAME record pointing to www.archive.is while CNAME RR on apex domains are usually not allowed in DNS... what make this even more interesting, i only see the CNAME RR when querying via 1.1.1.1 and not when querying authoritative servers for archive.is (EDIT: while repeating the query via 1.1.1.1 i also saw both A and CNAME record for archive.is in the response :S)
maybe the initial issue is just gone already? considering this is apparently happening in 2019 that does not seem too unlikely...
