guix-maintenance commit 7f59985566b384e31da7e6f1a36744e9edfba54f adds
nginx proxying for those /file URLs (‘guix publish’ 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):
--8<---------------cut here---------------start------------->8---
$ wget -q -O - https://mirror.hydra.gnu.org/file/hello-2.10.tar.gz/sha256/0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i | guix hash /dev/stdin
0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i
--8<---------------cut here---------------end--------------->8---
Guix commit 40f788b9f6184436d9cc36a4dd8e7d101cd2f0ba adds
mirror.hydra.gnu.org as a content-addressable mirror.
