If it collapses, lenders will own (in general) giant tip-up buildings with two separate substations tied to two different utility circuits, a shitload of generators and UPSes, a shitload of chillers and cooling towers, and miles of cable tray. Plus whatever computing hardware is inside.
I assume the excess electrical and HVAC gear would be stripped out and sold before converting the tip-up building into another yet another Amazon distribution center.
It’s not particularly useful infrastructure, unlike all of the dark fiber laid during the dotcom boom.
