As discussed yesterday on IRC, the 504 here was due to ‘guix publish’
being stuck on hydra.gnu.org, which is now fixed.

Nevertheless, I’ve started an upload to alpha.gnu.org/guix/mirror as you
suggested (should be there within 15 minutes or so) for two reasons:

  1. It’s safer, and it’s a critical package.

  2. Content-addressed mirrors are checked as a last resort after all
     the GNU mirrors have been checked.  However, Jan reported that some
     mirrors return 200 with bogus data, which leads to a hash mismatch
     error (this is because it’s guix-daemon that checks hashes, after
     the ‘guix perform-download’ has done its jobs; ‘guix
     perform-download’ thus doesn’t check hashes.)

Thanks for the heads-up!

Ludo’.
