The answer is that these kinds of problems result in transient errors.
Sometimes you can resolve the names, other times you can't.  It may also be
dependent on the version of nameserver you're running -- different
nameservers behave differently when running into these types of problems
(since Hotmail is a Microsoft service, maybe they're using Microsoft DNS
server rather than BIND, but I shudder when I contemplate such a
configuration).
