RE: Fire protection in ISPs and collocation facilities
Simple rule, make sure that you're upstream and the down-stream end has more bandwidth than the up-stream end. It's kind of the reverse of the internet. In the event that the inflow exceeds the outflow, hit the SCRAM switch before you fry something. This is the main reason I have it (SCRAM), but I'm damned if I can justify it for that reason. It's a lot easier to talk about fire. It should be left in the Fire codes. What are the four seasons in California? Earthquake, Drought, Fire, and Flood. You've no doubt heard about the "Oakland Hills Fire" but no one has ever talked about the mud-slides, in the Winter following the "Oakland Hills Fire", caused by the ground-cover being burnt off. In fact, no one hears much about California flooding. That's because it is a natural part of the ecology here and not as sexy as earthquakes and brush fires.

In Fairfax and Loudon Counties here in Virginia, fire codes require water for fire suppression (you can use other means, but you have to have water). So all the co-lo and exchange facilities here have pressurised water fire suppression. I have been surprised at how many of these do not have DRAINS for the water. In my real estate experience, whenever you have the possibility of water release, you will eventually HAVE water release. With no drains, that means you will have to move the equipment out to get the water out...
Its a catch-22. In Rochelle Park, a substantional amount of the flooding entered the building through the drains and plumbing. If you have openings for the water to flow out, the water can also flow in. On the other hand, there have also been colo's (in Virginia) with depressed/raised floors which turned into concrete pools submerging all the data cables and power cables below the raised floor.
Do I have a solution? No. I've thought about building in dry sumps and containment (i.e. like nuclear reactor buildings). But that has problems too.

Roeland, As a former "temp" resident of California (at Twenty-nine Palms MCAGCC) I can attest for the flooding. Believe it or not, the sand storms don't hold a candle to packing sandbags to keep a building from caving in as result of the rain. --- John Fraizer UCMC Ret EnterZone, Inc
