Lightning took out a modem and some nearby hardware here about a week ago. Residential. The distribution of dead vs damaged vs nominally unharmed hardware points very directly at the copper wire carrying vdsl. Modem was connected via ethernet to everything else.
I think the proper fix for that is probably to convert to optical, run along a fibre for a bit, then convert back. It seems likely that electricity will take a different route in preference to the glass. That turns out to be disproportionately annoying to spec (not a networking guy, gave up after an hour trying to distinguish products) so I've put a wifi bridge between the vdsl modem and everything else. Hopefully that's the failure mode contained for the next storm.
Mainly posting because I have a ZFS array that was wired to the same modem as everything else. It seems to have survived the experience but that seems like luck.
