There were no ALLOW or firewall changes made on any of the real-server
backend machines of the idd.unidata.ucar.edu cluster, so our first thought
is that there is some firewall/security perimeter block that is at/near
your machine.

Can you try running the following:

<as 'ldm'>
notifyme -vl- -f ANY -h idd.unidata.ucar.edu

and send us the output.  We will use the information from the listing
to see if the connection REQUEST actually is making it to any of the
backend machines of the idd.unidata.ucar.edu cluster.

Thanks in advance...

Cheers,

Tom
