Re: There's nothing quite like...
AC starts leaking in a LAN room,
Well, a computer room, not a dedicated LAN room, although it involved the LAN. And it wasn't much of a computer room either, merely a repurposed office where they had installed a raised floor to house a pair of VAX8200's.
The problem was the LAN getting gradually flakier, so I was called in to figure out what was happening, and solve it. After lifting a floor tile to check where the AUI cable went, it immediately became clear what the problem was: apparently the aircon had sprung a leak, and there was a serious quantity of a strange yellowish fluid under the raised floor. Pulling on the cable it transpired that the coolant had dissolved the linoleum flooring into something custard-like, engulfing a DELNI and some other unidentifiable stuff.
Getting a few AUI cables and a new DELNI, simply put on top of one of the systems, took care of the LAN problems; whatever they did with the custard was NMP.
