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. -- Thanks, Maxim
