The brief
Lauren Feiner reports from Loudoun County, Virginia, where the region’s ties to AOL and the internet helped create the world’s largest concentration of data centers.
The industry initially won community support by bringing tax revenue and funding public services, but its expansion has made electricity, transmission lines, noise, and zoning harder to ignore.
Loudoun’s by-right zoning allowed facilities to spread with limited additional approval, while growing AI workloads raised new questions about whether demand had reached a tipping point.
Residents including Vicky Hu and Jason Mello illustrate the personal stakes, from fighting transmission lines and lost trees to trying to soundproof homes against persistent noise.
Other counties now consult Loudoun as both a guide and a cautionary example, weighing moratoriums and new rules before data center development outpaces local capacity.
