[LDM #VBI-508834]: Acquiring LIGHTNING/NLDN data on new server

Hi,

The IDD LIGHTNING feed (AKA NLDN) is only available as a point-to-point
feed from the source of the data, UAlbany.  The machine that provides
the feed is as is set in you existing servers LDM configuration file,
striker.atmos.albany.edu.

Since the LIGHTNING data is proprietary, new sites or existing sites
that are bringing up the LDM on new machines must contact folks at
UAlbany to ask them to an appropriate ALLOW in their LDM configuration
file so that the new machine will be allowed to REQUEST the feed.  The
contact information for LIGHTNING feed REQUESTs at UAlbany is:

address@hidden

You may also want to CC Kevin Tyle on your request email:

Kevin Tyle <address@hidden>

It is not permissible to relay the LIGHTNING feed outside of one's institution,
so our top level IDD relay clusters, idd.unidata.ucar.edu and 
iddb.unidata.ucar.edu,
are not allowed to send this feed to anyone.

re:
> Can you please help me understand what my issue is?

You should revert your LIGHTNING feed REQUEST on your new machine to point
at the UAlbany upstream, striker.atmos.albany.edu.  After the folks at 
UAlbany get your feed request email, they should add the needed ALLOW
reasonably quickly, and data should start to flow.

Cheers,

Tom
