Greetings!

Thanks for the kind words.

Unidata is funded by the National Science Foundation to help make data 
available, but we do not have the resources to be a full archive center. Thus, 
we only are able to keep and host ~30 days' worth of data.

For a more extensive archive of data, you want to look at the National Center 
for Environmental Information (NCEI):

  https://www.ncei.noaa.gov
  https://www.ncei.noaa.gov/products/weather-climate-models/global-forecast

They maintain longer term archives of GFS, both in the cloud and available from 
a THREDDS server:

  https://www.ncei.noaa.gov/thredds/catalog/model-gfs-004-files/catalog.html
  https://registry.opendata.aws/noaa-gfs-bdp-pds/

Hope this helps!

Ryan
