Re: "While workers sorted out desks and networks and other niceties..."
I helped build a test platform in a DC in London, and there were only two small cages tucked away to one side where customer equipment could sit - the rest of the entire floor was empty - lots of football played with printer paper balled up and wrapped in tape ensued :)
Oh, and did I mention there was a pub about 10ft outside the door with a pool table and an excellent cook doing authentic Thai curries? Lovely :)
That is until M$ came along and bought the entire floor for xbox live :(
