Oh no - a data leak!

And when he got to the end of the cable run it disappeared into a solid brick wall

The only one I know is about the router where the protective boot would press a button on the router.

So this one time my house got struck by lightning. It caused over 10k in damages including some of the equipment in my homelab.

The lightning traveled through the coax on the modem (some how unaffected), into my opnsense, destroyed the pcie NIC, on both WAN and LAN side, managed to travel through my POE switch and killed every non-POE device, including my main workstations motherboard. The switch was still alive but POE function wasn’t working. After I replaced it, strangely none of the POE devices were affected and were working fine.

Since then, my coax has ground protections, two of them.
