LIghtning – It Goes Where It Wants, Regardless

My long absence from my Linux blog:

It’s been a busy 6 weeks on the farm. The first of September saw a huge storm roll through our area, and with it, a lightning strike that took out everything hardwired to our internal network!

We have a 60 foot tower on the farm, that is grounded with several ground rods. My office has what’s called a halo built into it, that usually protects everything inside from lightning strikes as well. Indeed, that tower has been hit many times the last 11 years with no damage.

Did the lightning hit the tower or my office building? Nope, it hit a network cable that run through a cable bridge between my office and the barn! The cable bridge is grounded, but rather than hit the grounded bridge, it hit the network cable that was laying in the bridge.

The resulting hit took out 2 servers, 5 desktops, 1 laptop, 1 television, 7 cameras, a Harris video switcher, my 2, DIN 3 internet relay units, and all of my ham radio equipment. Everything that was in some way hooked to the wired network!

Being in the state insurance pool, filing a claim would be useless, and with my high deductible, wouldn’t help much anyway. So for the past 6 weeks we’ve been cobbling everything back together from scratch!

Restoration was made a bit easier, in that none of our hard drives were damaged, so as new computers were purchased, We were able to restore all of our data with zero loss.   For our replacement ownCloud server, I just plugged the old drive right in and booted it up!

Next, we spent a couple of weeks trenching new conduit from our goat pen, into the house, and have moved all of our streaming video equipment and control systems inside. Further, we’ve totally isolated that system from the rest of the network.

All the new computers now run Linux Mint 18, and we’re very happy with the refinements over version 17.3.

So yes, do take precautions with your equipment where lightning is concerned, but they don’t always work.
