DNS resolving issues with AT&T Customer Resolvers

Hi all,I have a client bridgecatalog.com and it seems like customers with AT&T are unable to resolve his Domain. Maybe I am just overlooking something here but it seems like all should be working. Looking at outside tool things look ok too. http://dnscheck.pingdom.com/?domain=bridgecatalog.com
(except the SOA hostmaster () solarek com e-mailing issues I see now)Other domains seem to work fine. So it isn't just everything is down. One of the end-users I was working with currently has an ip of 99.7.225.25. Power cycling the modem did not change thing. I also flushed DNS. If I change to google's open resolvers things work fine. But not with default resolvers to client.
Anyone at AT&T that could check that the resolver's your clients are using are able to resolve. (Home / SMB connections, etc)
I am not sure the best way to go about trying to look into this issue if other have suggestion I would also appreciate it.
Sincerely, -- Mark Keymer
