Hmm... we REQUEST GEM data from ldm.meteo.ec.gc.ca, not ldm.weather.ec.gc.ca.
But, we are currently unable to get to ldm.meteo.ec.gc.ca:

% ldmping ldm.meteo.ec.gc.ca

Unable to receive; errno = Connection reset by peer

This should mean that there is some problem at CMC.  We will contact folks
there to troubleshoot.

Aside:  it is possible that their problem occurred at the same time (or because 
of)
they contacted us about a problem receiving NEXRAD3 data from us.  That problem
turned out to be something that they found and fixed on their side.  I wonder
if the fix also knocked-out their feeding of the GEM data.

I will need to touch base with Jeff Weber here in Unidata to see if he
has a better handle on the change from ldm.weather.ec.gc.ca to
ldm.meteo.ec.gc.ca.

Cheers,

Tom
