Blamo! (A tale of lightning damgae)

cletus

We had a nearby lightning strike yesterday at work. What was weird was that a fraction of a second before the lightning strike there was a snap that could be heard in various parts of the building. The snap turned out to be arc over in various parts of our ethernet network!

Apparently the static buildup preceding the lightning strike caused a big potential difference between the two floors of the office. When the difference got big enough...bam! Three hubs (all the same brand :scratch) lost their uplink ports, two PC's lost their ethernet cards and one of our satellite receiver/file servers lost it's ethernet port. One 12 year old PC, not on the network, lost an I/O controller.
