I can't seem to reproduce the original issue, which was that an offline
server would slow down fetching of substitutes by repeatedly trying to
reach it, at least when setting e.g.:
--8<---------------cut here---------------start------------->8---
127.0.0.2 ci.guix.gnu.org
--8<---------------cut here---------------end--------------->8---
In my /etc/hosts file to simulate it's unreachable, with at least
another substitute server available in my --substitute-urls list. It
goes right to that second server without loosing any time.
Closing for now, we can always reopen the issue if it manifests itself
in the future.
