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.
