Is this the future of America?
The Verge examines how Loudoun County, Virginia, became "Data Center Alley," the world's densest cluster of data centres, and the growing local and national backlash this has provoked. What began in 2007 as a deliberate economic strategy to diversify county revenue away from residential property taxes has, aided by the legacy infrastructure of AOL and the dot-com era, turned the county into the physical backbone of a large share of global internet traffic — and more recently a magnet for the infrastructure needed to power generative AI.
The transformation has brought substantial financial benefits: data centres funded 22 new schools over 15 years, generated tax revenue that exceeded the county's 2024 operating budget by $35 million, and helped cut the residential property tax rate from around $1.29 to 80 cents per $100 of assessed value since 2008. The county now hosts roughly 250 data centres across a fraction of its 515 square miles, with estimates suggesting up to 70% of global internet traffic once passed through the area. However, as the current AI-driven data centre boom accelerates nationally (with around 3,000 data centres already built in the US), residents in Loudoun and beyond are increasingly voicing concerns about the disruption this rapid growth brings to daily life and local communities.

Loudoun County, Virginia, sits close to Washington DC and, thanks to infrastructure left over from AOL and the early internet boom, became a hub for data centres from the mid-2000s onward. County officials pursued this deliberately, seeing data centres as a way to raise tax revenue without relying so heavily on homeowners. Over time the county grew into the world's most concentrated cluster of these facilities, earning it the nickname "Data Center Alley."
Data centres are the large, power-hungry buildings that house the servers running much of the internet, and increasingly the computing systems behind artificial intelligence. Loudoun's cluster is significant not just for its size but for the scale of internet traffic it has historically handled, and for how central it has become to the infrastructure needed for AI development in the United States.
The arrangement has delivered clear financial benefits to the county, including new schools and lower property taxes, funded largely by revenue from the data centre industry. At the same time, the rapid pace of construction, both in Loudoun and in similar boom locations across the country, has increasingly raised concerns among residents about the effects on local life, setting up a wider debate about how this kind of growth should be managed.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Advocates for continued data centre expansion argue that Loudoun County's experience shows genuine, measurable public benefit: two decades of steady tax revenue has funded 22 new schools, pushed county coffers $35 million above the 2024 operating budget, and nearly halved the residential property tax rate. They see this as a rare case of a local government successfully diversifying its tax base away from homeowners, generating jobs and infrastructure investment, and positioning the region as indispensable to the digital and AI economy that increasingly underpins national competitiveness and everyday life.
The case against
Critics, including many long-standing residents, argue that the pace and scale of data centre construction has outstripped the county's capacity to protect quality of life, citing strain on the electricity grid, rising water use, noise from cooling systems, loss of green space and rural character, and the sense that a handful of tech firms now wield outsized influence over local land-use decisions. They contend that even substantial tax revenue does not fully offset these cumulative costs, and worry that what happened in Loudoun is being repeated nationally without adequate public debate about whether communities actually want to become the physical infrastructure for someone else's AI boom.
