The machine appears to be OK; it's online again now.

The network switch that it is connected to has disabled that specific port.

This may be a glitch, but it's unrelated to the machine itself.

I've temporarily connected cfarm109 to a different port on the switch.

I've also connected a USB debug cable to diagnose future issues.
