Full DCPI breakdown →DC Hub analyst read on Ashburn — the market this facility sits in (full deep-dive →).
Ashburn remains the dominant hyperscale hub in Northern Virginia, hosting 8,662 MW across 318 tracked facilities, but power availability and infrastructure constraints are now the binding limiting factors for growth.
