It's more than that, it's also a giant office building.

Here is the previous (large) HN discussion on this topic, there is nothing new in the blog post linked to here: http://news.ycombinator.com/item?id=1965686

I know of a large holding company of luxury jewelry goods that has space in the building. For them, its not just cubicles. It would be a very poor publicity stunt to kick everyone out of the building in order to install racks and servers in every room.

Other companies have enough leverage in non-internet related fields to cause a big shitstorm if it was to happen. If this is a long term approach I could see them not renew or assign new leases when current tenants vacate, but you will not see press releases. I also have no association with this story, so I can only speculate as well.

It already has entire floors of co-location space. That's what people are referring to.

Google might have some interest in co-locating some gear there, but they would never turn it into a DC proper (it's nowhere near large enough).
