yeah, ok, the situation appears slightly more messed up than originally
surmised.

the dcXlbs1 boxes are the ones pointed to by the root.  unfortunately,
they think the dns0X boxes are the nameservers (though that doesn't matter
if you don't ask dcXlbs1 for NS records).

also of note is the SOA serial number is 20050503 (four weeks ago).
also interesting is that the whois/registry for uls-prod.com says
that it's expired.
