They should be using the local IP instead of routing through the
internet, so /etc/hosts should contain an entry for

141.80.167.131 ci.guix.gnu.org

(We have the same entry on the other build nodes hosted at the MDC.)

“guix deploy” did not work on these nodes due to a serious problem: they
were given *some* x86_64 binaries to execute, so deployed systems were
unbootable.  Since we don’t have a serial interface through which you
could debug this remotely, please make sure not to deploy a broken
system.  I’d like to avoid trips to the data centre.
