First, apologies if this is not the correct list; if I should direct this 
question elsewhere, please let me know.

Up until this week, we had been ingesting NAM212 girds (40km resolution) using 
the pattern: 

HDS|CONDUIT     ((/mNAM|/mNMM).*#212|prod/nam.*awip3d)

We received the grids for 0-84 hours; however starting Wednesday or Thursday, 
this was truncated to 60 hours on 00Z/12Z runs and 48 hours on 06Z/18Z runs.    
I'm unable to find any documentation of: 

a) Whether this is a permanent change (my guess would be yes) and 
b) If there is a similar replacement or upgrade that goes out to 84 hours.  

We are seeking answers to both of these questions. 

(As a side note, I noticed we may have a problem with receiving data on the 
CONDUIT feed - these charts to do not look good - 
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+twister2.sbs.ohio-state.edu
 )  

Using notifyme on the CONDUIT feed, I found a product awip3d78 that does 
provide grids to 84 hours -- however, I'm unsure of the NAM product with which 
these grids are associated.   What is the best way to determine this? 

This page: http://www.nco.ncep.noaa.gov/pmb/products/nam/  seems woefully out 
of date (hasn't been updated since Oct 2011). 

Thanks in advance for any assistance or guidance,
