It seems my network (WiFi managed with nmcli (network-manager)) had some
problems resolving DNS at that time. I cannot reproduce it anymore, so I
think this issue can be closed. We have a similar issue in 26833, which
for some reason is not listed on our Debbugs tracker anymore (still
available here: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26833).

I could easily reproduce that one in the last days, with Bayfront
seemingly down it was crashing Guix with a "no route to host" error or
similar.
