Re: Rain, Rain, Go Away
A friend of mine had a similar situation, a council's server room was located underground directly under some public toilets. Every time they overflowed or there was a bit of rain, it rained in the server room and it filled up with several feet of water.
Their solution: Raise the servers up AND build a corrugated plastic roof over the servers with guttering to move the rain away. Wellies were provided at the door with explicit instructions to not ask what was in the water!
