IAD24 at 43830 Devin Shafron Drive in Ashburn is Building F, and at 103,500 sq ft on a single storey it is both the smallest and the newest of the Devin Shafron group, completed in 2011 against neighbours built in 2001. It runs duplicated 2N power paths with N+1 on the cooling side. It sits on a 98-acre campus that Digital Realty puts at 500 MW of total capacity across all its buildings — the only load figure the operator publishes anywhere in Northern Virginia, and a campus number rather than a building one. For a buyer the argument here is a smaller, later-generation hall with the whole Loudoun campus and its carrier ecosystem behind it.
