Thanks for your inquiry.

Yes, things have gotten much better in the last week.  There have been
problems with our PSN which may have been part of the problem.  The
symptoms of the PSN problem is messages from the PSN to our gateway
which indicate insufficient resources in our PSN for connections to
some sites.  A trouble ticket has been issued in Mike Muuss' name for
this problem.  It is still open at this time and we are still getting
these advisory packets from the PSN.

The behavior I noted in my message to the list was not due to problems
with a specific host (or so it seemed).  Both had proper routes to the
other and could be pinged from a third host (usna.mil).  These pings
had reasonable round trip times.  The aberrant behavior was only
between ardec.arpa and hosts at BRL.  We could occasionally get
packets through by starting a pinging from ardec.arpa.

Anyway, the problem I reported seems to have been resolved since ping
round trips are now reasonable (< 500ms).  Our PSN is also being
reloaded tonight with new software, presumably to fix the problem with
insufficient resources.
