We recently moved over to a new server, and (unlike the previous one)
this should be reliable.

All that virt-builder is doing to download the files is running the
curl command:

https://github.com/libguestfs/libguestfs/blob/a4e3b7c0598370d8d068b21909da95b6031eb688/builder/downloader.ml#L115

Could there be a problem with curl?

I don't really recommend this, but the filename is just
~/.cache/virt-builder/<os-version>.<arch>.<revision>
so as long as you get the filename right virt-builder should see it.
