Re: Building a NOC

[Chris Liljenstolpe <cds () wwsi com>]

Greetings,

        We have a similar set up down here at a research station in Antarctica.
Due to interesting environmental conditions and the fact that the NOC is in
an original metal building built by the Navy in the late 1950's, we get
leaks when it gets warm enough in the summer to melt the snow accumulation
on the roof, it then finds spaces between the bolts that hold the roof to
the metal i-beams that provide the roof structure.  We then get minor rain
storm in the NOC as the water comes through the false ceiling.  We have
been trying for a few years to get it fixed (lack of funding, asbestos
problems, etc.) so we have a plastic tarp and roller system we devised - it
works - ugly as hell, but we don't have water raining into the router
anymore :)

        Chris
