Has Cobalt/Sun ever addressed this issue?

We have seen this from UUnet Cache DNS Servers and several other networks.
We haven't tracked down is it is a communication problem with Cobalt Servers
running bind but it usually clears up in a day.

If you run dig, you will see that the root and cobalt name servers respond
correctly but the UUnet/Worldcom servers do not see the records.  This has
the effect of domains dropping off the net for a day or more.

If anyone has solved this, please post.  Worldcom's response was "Use
another DNS".  This of course is not a valid solution for the other 50
million Worldcom customers.

None of what you did should have made a difference to Frderik.

His system isn't using the named daemon on the RaQ at all; the
resolver's going right out the box to uu.net.  The problem is probably,
as he suggests, is time-out based on slow connectivity.
