The URL displayed during the download was mirror.hydra.gnu.org.

It was a binary download, not source. At least, I don't recall anything
about compiles at any point (and I'm sure it didn't take long enough to
do that; one package was icecat which I'm sure wouldn't have downloaded
at 90k/s then compiled in less than 15 minutes (fwiw, according to my
build logs firefox takes about 2 hours to build, so unless icecat is
magically orders of magnitude faster to build, then I'm sure it was
just a download + install, and not download + compile + install)
