Yikes. I see Isilon and I think someone just spent 500k where they could have spent 75k and used MogileFS or similar. I suppose 37 signal's profit margins are good enough that it doesn't matter, but I'm glad it's not my money.<p>Moving to their own servers makes sense though. No doubt that's going to save them over paying a huge premiuim for Rackspace. With three full-time people it's a good move.
tldr: they moved from rackspace to their own colocated servers at someone else's datacenter, they didn't build a new datacenter. not sure why anyone would really care about this...
