How Loudoun County, Virginia Became the World's Data Center Capital

Loudoun County, Virginia, home to roughly 250 data centers, handles an estimated 70 percent of global internet traffic, earning it the nickname 'Data Center Alley.' The transformation began after 2007, when economic development official Buddy Rizer leveraged leftover dot-com era infrastructure — empty buildings and buried fiber optic cable — to attract tech investment. The strategy paid off handsomely: data center tax revenue exceeded the county's operational budget by $35 million in 2024, funded 22 new schools in 15 years, and helped cut residential property tax rates nearly in half since 2008. For years, most residents barely noticed the industrial expansion happening around them, benefiting quietly from lower taxes and better public services. However, as the national data center buildout accelerates — driven largely by cloud computing and AI demand — the impacts on daily life in Loudoun are becoming harder to ignore, fueling growing local and national scrutiny.
