It's normal for different buildings to have ground potential differences which aren't very many volts, but can supply many amps. It's less normal for the voltages to exceed a thousand volts, but in case of a lightning strike near either building it can definitely happen. | |

I worked at a company that replaced an entire small office of gear after a lightning strike took out every Ethernet-connected device in the building. Exploded chips, etc. The lightning supposedly hit very close to a buried Ethernet cable. | |
