When investment bank Bear Stearns collapsed in 2008, there was nothing left of value to auction off except its data centers. JP Morgan bought the company's carcass for just $270 million but the only thing of value was Bear's NYC headquarters and two data centers.
Since then there have been numerous sales of data centers under better conditions. There are even websites (Datacenters.com, Five 9s Digital) that list data centers for sale. You can buy an empty building, but in most cases, you get the equipment, too.
