My expectation is that if the SJTUG server fails, = it should fall back on using the Cuirass server. So my problems are two-fold: * Apparently the SJTUG mirror sometimes acts in ways that aren't quite how = Guix expects it. Either SJTUG or Guix has to be fixed so they talk in comp= atible manners. * Multiple Substitute URLs are not useful for the mirroring configuration w= here one server is temporarily unable to properly serve; further servers ar= e not checked. I'm still not satisfied with this solution overall. Yes it's fast but it's= imperfect. I recently had to rebuild an OS (because I was dumb; the Guix language for = shepherd services can easily lead you deadlocking shepherd itself) and had = supreme difficulty reinstalling, because the Berlin server was too slow (wo= uld have taken ~10hours downloading everything) while the SJTUG server was = unreliable and would consistently break the automated install. I had to `g= uix system build --fallback` separately and *then* `guix system init` manua= lly. Thanks raid5atemyhomework
