But then, what if it really *is* a temporary error, and their
DNS server was just down at the moment.

If they answer you on one rr, but not the other, the server isn't down.

Usually you ask your own forwarding (and caching) DNS server about the RRs. If that server has one RR still cached but can not reach the authoritative server for the domain, you will get cached answers to some queries and timeouts to everything not in your DNS servers cache.
