guix-maintenance commit 7f59985566b384e31da7e6f1a36744e9edfba54f adds
nginx proxying for those /file URLs (=E2=80=98guix publish=E2=80=99 is now =
running on
hydra.gnu.org, though we only use it for those /file URLs;
mirror.hydra.gnu.org proxies and caches those requests):

Guix commit 40f788b9f6184436d9cc36a4dd8e7d101cd2f0ba adds
mirror.hydra.gnu.org as a content-addressable mirror.
