I can't get any answer from 12.160.102.130 ("connection refused"), and
the other delegated nameserver for the domain
(SMTU.MT.RS.ELS-GMS.ATT.NET) doesn't appear to know anything about it.
The former issue is probably due to a networking and/or firewall problem,
and the latter issue is probably a case of the AT&T server either a) not
being configured properly as a slave in the first place, or b) having
expired the zone because it couldn't contact the master for an extended
period of time.

By the way, thanks for posting *real* zonefile/named.conf information
instead of this "foobar" or "domain.com" crap. It's a refreshing
change...
