Very wise.
Now there is a lot more to disconnect. Network cables
to all the
machines, two of them to the linux box hooked to the cable modem, various
printers, monitors and speakers not always hooked to a UPS due to lack of
plugs or capacity. I imagine any one could be an entry point for a
surge.
If the network cables are all inside the building and aren't too long,
they're probably fairly safe.

OK. I believe one or two terminals were also scorched.
That was probably due to current induced in the serial lines. On campus,
we used to have lots of serial cards and terminals blow up every time there
was a big thunderstorm, because the outdoor cables ran in overhead ducts in
covered walkways. The network is usually fine, though (it's either
underground or fibre between buildings).
