Our files for the NAM on the 212 grid coming through on the NOAAport feed were 
definitely smaller recently - some I'm sure due to the internet issues at 
NCEP/College Park

The data that came through on the CONDUIT feed seems complete for today's 12 
UTC run, so not sure what was different..

Subject: [ldm-users] Missing grid data today

Has anyone else experienced a significant amount of missing grid data (at 
least) today? I noticed that I missed quite a bit of NAM (GRID218) data from 
today's 12Z cycle, and I'm not sure why. I checked our latency, and we had a 
few spikes up to a few minutes, but that's it. I see quite a few entries in my 
ldmd.log file showing primary/alternate transfer-mode switches. Is that normal?

Thanks for any input.

Matt
