Hi,

The facility that houses the machines that comprise the iddb.unidata.ucar.edu
cluster experienced a power outage at 11:42 MDT at this time.  ETA for return
of power is unknown.

The facility that houses the machines that comprise the idd.unidata.ucar.edu
cluster is _not_ experiencing any power problems, and I just checked 
accessibility
from a machine at the University of Wisconsin's Space Science and Engineering
Center in Madison, WI, and it can connect to idd.unidata.ucar.edu with no
problems.

There should not be a problem connecting to idd.unidata.ucar.edu.

What are the results of the following run from the 'ldm' account on
one of your machines:

notifyme -vl- -f ANY -h idd.unidata.ucar.edu

reL

Again, iddb.unidata.ucar.edu is not accessible due to a power outage
at the NCAR Mesa Lab where the cluster is housed.  idd.unidata.ucar.edu
should be accessible to your notifyme and/or feed REQUEST(s).

Cheers,

Tom
