Reading Bob’s blog entry about lightening over here made me think about lightening and DSL modems. Bob’s quite right about computers most often getting lightening damage through the phone lines not the power lines. The fact that most DSL services use external modems actually provides a extra layer of protection for your computer. For lightening to travel the phone line and damage any of my computers it would have to go through the modem and my Ethernet switch. I’m not an electrical engineer but I suspect this isn’t very likely. Of course it’s still a good idea to unplug your DSL modem during a storm.
