Actually, berlin.guixsd.org and ci.guix.gnu.org are the same server, and
mirror.hydra.gnu.org was decommissioned a while ago. The second server
for substitutes is https://bayfront.guix.gnu.org.

I think the best option would be to make sure you run 'guix pull'
targeting a derivation which has substitutes. If you check here¹ you can
see if there's a substitute already available for armhf-linux and run
'guix pull --commit=the-commit-listed-in-the-link'. Right now, that
would be 42a2ee1f9294614bd85892f2cc7318afb80b174c, which is actually the
latest commit.
