The build farm’s log file is at <https://ci.guix.gnu.org/log/XYZ>, where
XYZ is the basename of one of the outputs of the derivation of
interest.  For example:

  https://ci.guix.gnu.org/log/cghjx256ls2hrpcjbv65vnmvqszddh4i-rust-1.24.1

Unless you have built it locally, the following command gives you the
URL:

  guix build address@hidden --no-grafts --log-file

Now, the Cuirass Web and HTTP interfaces certainly leave a lot to be
desired, but you can help!  :-)  See Ricardo’s recent call for help on
guix-devel.

We’re now primarily focusing on ci.guix.gnu.org (aka. “berlin”), which
has more CPU power, so hydra.gnu.org may lag behind.

Thanks,
