Very wise.

If the network cables are all inside the building and aren't too long,
they're probably fairly safe.

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).
