Data Center Alley
Northern Virginia's "Data Center Alley", centered on Loudoun County, hosts the world's largest concentration of data centers. The region's proximity to Washington D.C., abundant fiber connectivity, and favorable business climate made it the epicenter of the internet. But explosive growth has triggered unprecedented community opposition.
Opposition Hotspot
Virginia leads the nation in data center opposition activity. Multiple counties have tightened zoning, and billions in projects face legal challenges.
