Sounds like a DNS caching problem.  Since you're running BIND 8, you
should have dig (better than nslookup).  So next time it happens try:

dig hotmail.com any +norec

That will show you what is in BIND's cache for hotmail.com (the +norec
will make it a non-recursive query).

My guess is that your cache is getting confused somehow and is failing
to look up hotmail.com.  Why?  Well, since hotmail in their infinite
wis-dumb has put 30 minute TTLs on their in-zone NS records, I suspect
that has something to do with it....

You may want to consider moving to djbdns instead of BIND.  It probably
deals with this better.
