Use the 'NSLOOKUP' utility.   Ask for the 'type=SOA'
("start of authority") record for the domains 'SSP.NMFS.GOV' and/or 'NMFS.GOV'.
 
You'll get the answer that [log in to unmask]
is the ID of the "responsible" person.
 
Or, contact the [log in to unmask] ID listed in the "transcript"
which you posted.

Use NSLOOKUP to find the four 'TYPE=MX' records for 'SSP.NMFS.GOV', namely:
 
  SOLIDSPARC.SSP.NMFS.GOV, preference=0
      CCGATE.SSP.NMFS.GOV, preference=10
     FRE2SUN.SSP.NMFS.GOV, preference=20
    KINGFISH.SSP.NMFS.GOV, preference=30
 
Notice the "preference" settings.
 
They indicate the order in which the hosts are to be contacted,
in order to try to send each piece of E-mail,
i.e., SOLIDSPARC should be contacted first.
If SOLIDSPARC does not open a connection, then CCGATE   should be tried.
If CCGATE     does not open a connection, then FRE2SUN  should be tried.
If FRE2SUN    does not open a connection, then KINGFISH should be tried.
 
As a side point, ask NSLOOKUP for the names of the hosts which provide
DNS service for the 'SSP.NMFS.GOV' domain, and you'll get the answers
'SOLIDSPARC.SSP.NMFS.GOV' and 'NS2.PSI.NET'.
 
Now, the transcript you included indicated that the connection was
made to 'FRE2SUN', i.e., the "second-alternate" server,
which implies that both the "primary-server" ('SOLIDSPARC')
and the "first-alternate" server ('CCGATE') were unable,
or unwilling, to open a connection.
 
I would take it as a "bad" sign when 50% of the machines are "down",
especially when one of the "down" machines is one of the DNS servers
for the domain.
 
The only "cure" for the problem is to prevent those machines from going "down",
which, of course, isn't very feasible, since they seem to be functioning
as an inter-dependent "cluster", i.e., if one machine in the cluster goes
"down", then the services it was providing are no longer available for the
other machines in the cluster.
