DNScheck.com shows timed out waiting for data

So I am getting ready to add a slave server to my current system for uptime. But I decided to run a check on the master and it shows timed out waiting for data?? I don't know what the problem is since we are up and running and in the past this error didn't show up, I can NSlookup and dig it all fine. Any ideas. sportuniform.com is one of the sites I get the error. Um virtual hosting, apache w/ modrewrite, and mac os x server. Thanks


Also for the slave server, I just got some more static IP's from another provider and there default name for the IP's adsl-69-153-213-97.dsl.hstntx.swbell.net

and I need to make it NS2.kzreuslts.com
I have updated tucows
and talked to them to get them to change it , but after waiting on the phone for an hour and a half, I gave up. what other things can I do to change the name of my newly aquired IP's I did the master a while ago and have forgot.
THanks again

I check sportuniform.com at www.dnscheck.com an I don't
see any problem. At what section you see the problem?
If you want to change the PTR record for your IP, you need
to contact your DSL provider, not your domain registrant.

I see the dig on that site is fine,
this is from www.checkdns.net - it runs a few tests, I can't really see a problem but it never makes me feel comfortable to get them.
for that site it comes in the section Web servers IP.

Yeah the idiots at sbc, I couldn't quite remember how I did it orginally and wanted to make sure I wasn't the idoit on the other line calling them idiots. Thanks.
