Hi Harry,

After seeing your inquiry this morning, I took a look at the
real servers in the cluster idd.unidata.ucar.edu.  One node,
which apparently had been handling freshair1, was showing
lots of errors of the kind:

Feb  7 22:53:22 uni17 freshair1.atmos.washington.edu(f[18754] NOTE: feed or 
notify failure; HEREIS: RPC: Unable to send; errno = Connection timed out

These errors ended at 23:09:58 UTC last night.

A different cluster node was and continues to handle connections
from freshair2.  Its LDM log file does not show the problems
that the other was indicating for freshair1, but it does show
repeated reconnection attempts up until 7:22:19 UTC.

Can you confirm that freshair2 continues to have problems
receiving data from idd.unidata.ucar.edu?  If it is still
having problems, I will restart the LDMs on both of the
cluster nodes that are handling connections to UW.
