Starting last week, AAAA queries for domains are not "failing" correctly when the domain being looked up is a CNAME for an A record.
Instead of getting back a response indicating there is no AAAA record, the resolver continues to look for a AAAA record until a timeout (a minute or so), where it then switches to looking for an A record, which is found immediately (as a CNAME).
Here it is even more simply, the first query should give something like the third.
