The funny thing is that after a recent remodel the router got moved and we don’t know where it is. It still works but nobody knows the exact location. It may be in the ceiling or the floor.
That reminds me about the story of a University that an old DEC VAX that got walled up during a remodel. Machine kept running and no one notice. A decade later another remodel came along and they tore down the wall to find the machine just happily running.
