We get quite a few near-miss strikes here every summer; the power
goes out, the air conditioning quits, the machines break ... and now
the Ethernet transceivers get zapped.  Apparently they are indeed
the weak links.  We have one interbuilding cable; each summer we
lose several transceivers in one or both buildings.

In two years, we have not yet had any Ethernet boards quit immediately
after a thunderstorm.  I think the count of dead transceivers is
well into the tens, though.
