Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

But that notice

http://www.nws.noaa.gov/om/notification/tin07-59gfs_upgrade_unifiedpost.txt

says:

"THE PRIMARY IMPACT TO CUSTOMERS RECEIVING THE GFS WILL BE THAT 
THE DEFAULT PRECIPITATION TYPE ALGORITHM WILL CHANGE"

and further

"THE PRODUCTS/GRIDS WHICH ARE DISSEMINATED TO NOAAPORT AND/OR THE 
SATELLITE BROADCAST NETWORK /SBN/ WILL NOT BE CHANGED IN VOLUME 
OR CONTENT."

So there appears to be more to this than that . . .
