Recent changes to UltraDNS, problems?

Mon Aug 23 23:53:13 UTC 2004

Has anyone else noticed any strange problems lately when querying 
UltraDNS for name server records?

I have a few scripts that seem to have broken in the past week.  A 
simple PERL script that looks up NS records from the root servers, which 
worked fine last week, suddenly starts reporting that the query is 
returning an empty answer.

If I change it to any other TLD servers/domains, it works fine.  What is 
even more strange is that when I use dig, the lookups are just fine. 
(most of the time)  Can anyone at UltraDNS (or anyone else for that 
matter) shed some light on what might have changed/broken?

#!/usr/bin/perl

use strict;
use Net::DNS;    #version 0.48

my @tld = ("tld1.ultradns.net", "tld2.ultradns.net");
my $res = Net::DNS::Resolver->new;
$res->nameservers(@tld);

my $query = $res->query("adaconline.org", "NS");
if($query) {
     print "It worked!\n";
} else {
     print "It failed!\n";
}

exit;

In the above case the query always returns undef and the errorstring 
returned is no error.  My initial thought was a bug in Net::DNS, but 
I've also heard from others they've started noticing strange lookup 
problems when asking UltraDNS directly for answers.
