I don't know anything about gnu.org's availability, but if you 
want to download sources ahead of time you can do so with the guix 
build --sources flag. It will download the source of a package or 
derivation and put it in the store. For instance, you could 
download the sources of a package manifest and all of its 
transitive dependencies with the following:

guix build --sources=transitive --manifest=manifest.scm

I'm not sure how something fully offline would work though, as the 
sources for all Guix packages would take up a massive amount of 
disk space. The number of packages each person would want offline 
would also depend on how much disk space they are willing to give 
up.
