It’s tempting to follow the lead of traditional distros when it comes to

However, Guix is very different from these: on the build farm, we build
several new store items per minute, and we aim to distribute them to our
users.  This is quite different from distros that upload .deb, .rpm,
etc. files much less frequently.  Their mirroring process is thus fairly
similar to good ol’ synchronization over rsync and the like.

For Guix I think a caching proxy and a CDN kind of model is a better
fit: it’s good fit for the publication rate of store items, and a good
fit for ‘guix publish’ which uses HTTP.  Furthermore, the build farm
doesn’t expose anything like rsync, which makes it hard to imagine a
“traditional” mirroring process.
