Domain only resolved locally... Confused.

[Kendall Koning]

I've got a confusing situation where one of our hosted domains only
resolves from our own servers, even though everything looks fine @
internic.  I'm running BIND 8.1 on Debian 2.1...

A local dnsquery looks like everything is set up correctly, and
everything resolves correctly on the local nameserver.  So the next
thing I check is internic, and whois is pointing at the correct
servers...  We got hundreds of other domains on this server that sure
look like they're set up the same, and they all work...  Am I missing
something obvious and just need a smack on the head?  

Any pointers or RTFMs would be appreciated.

Details below.

Another local ISP's nameserver doesn't resolve the domain

The zonefile for this domain looks like:

And the entry in my named.conf
