Just so you know: we=E2=80=99re aware of this problem and agree that it nee= ds solving. Ricardo (Cc=E2=80=99d) has helped in the past set up rsync on ci.guix.gnu.org so that someone could rsync /var/cache/guix/publish to a server in China. I think we have most of the pieces more or less in place. > Then a mirror site can simply pull the directory > /var/cache/guix/publish/nar from the Berlin server and serve this > directory through a static HTTP server.

The simplest solution for now (I think that=E2=80=99s what Ricardo & co. ha= d in mind) would be for you to retrieve /var/cache/guix/publish on your server, as is, and then run =E2=80=98guix publish=E2=80=99 on your sever: i= t will know where to find files. As I wrote to Jonathan, you can/should also run nginx on top of that as a proxy to your local =E2=80=98guix publish=E2=80= =99. Ricardo, can you remind us what the next steps would be? Does that make sense? Thanks, Ludo=E2=80=99.
