[IDV #BIG-535678]: Where can I find GFS data older than 45 days old?

The lead.unidata.ucar.edu server has been upgraded and the 0.5 degree GFS now 
works.  We're still looking into the 1.0 degree forecast hours, but if you want 
1 degree, just use a stride of every other point on the .5 degree. ;-)

Let us know if you have any problems with that.
