If by PRI you mean large ISDN circuit with lots of B channels, then I
understood you correctly.

Did anything happen to your RaQ? Did it have any problems at all? Or did
its upstream connection just fail temporarily?

It sounds more like Sprint is having DNS issues, and your salesperson is
blowing smoke up your ass (pardon my French).

Do an nslookup from your server ("nslookup - server.domain.com") without
the quotes and where server.domain.com is replaced by the name of your
RaQ. This will open nslookup in interactive mode (read the man pages for
more detail) and you can then enter domain names to your heart's
content. See if all those resolve properly.

Now, do the same thing using Sprint's DNS server (this is probably one
of the two DNS servers you configured your RaQ to ask when it doesn't
know an answer). See if they resolve correctly. If they work from Sprint
and not from you, then you may have DNS issues. If they don't work from
Sprint, they're the problem.

Your DNS shouldn't go nuts just because your uplink died. That doesn't
make sense.
