When I arrive, the problem is still occurring. Tests show transmission errors, but the connections seem fine. As a safeguard, fish changes the modems at the main bank and the remote branch. They check the line and can see problems, so they dispatch a technician. A week later, same problems, same bank, more rain.
Fish calls again, phone company dispatches tech again.
So fish and tech brave the downpour to check switches and wiring at the building. The wiring is all new, and they can't find a problem. Then fish spots a door next to all the new wiring. And it's soaking wires that are so old, they're covered with paper insulation. And wet paper insulation doesn't insulate very well.
