Working at a college in Oregon, we had a significant amount of snow/rain one winter and spring and facilities reported to IT that one of the dorm's basement was flooding. We had equipment there that was my responsibility, so... sure, send the 20-something network guy down to a flooding basement.
Luckily, the drains were working, so not much water standing, more like flowing - from the service tunnel into the 'room' on which the network equipment was housed. There was more than one kind of flow happening on that modular HP ProCurve 4000 switch! Soaked. Blinky lights, just humming along like normal.
