Hi,

re:
> Is your radar feed down this morning?  

No.  I just checked and both the NEXRAD Level 2 and NEXRAD Level
3 feeds are distributing products normally.

This log message shows that the attempt by the LDM on mammatus to REQUEST
a feed did not make it to idd.meteo.psu.edu.  Since the relay cluster at
Penn State (idd.meteo.psu.edu) is not under our control, we recommend that
you try adding a redundant feed to one of our top level IDD relay clusters,
idd.unidata.ucar.edu:

<as 'ldm'>
in the LDM configuration file ~ldm/etc/ldmd.conf

Change:

REQUEST  NEXRAD3 ".*"  idd.meteo.psu.edu

To:

REQUEST  NEXRAD3 ".*"  idd.meteo.psu.edu
REQUEST  NEXRAD3 ".*"  idd.unidata.ucar.edu

After making any change(s) to the LDM configuration file, you will need to
stop and restart your LDM for the change(s) to take effect:

ldmadmin stop
ldmadmin start

Cheers,

Tom
