Were you able to replay a scenario in which a substitute server is made unreachable? That's the information that I'd like to have/see before closing. I don't come across unreachable substitute servers often, and can't think of a way to easily test this. I could make it hang by dropping the input/output connections with iptables to a remote guix publish server, but then SSH also hangs, so perhaps that's expected. I'll try to configure a couple local machines to act as publish servers, and disconnect them from the network to see what happens. Thanks, Maxim
