This is the first in a series of stories looking at the Northern Virginia data center market, including how data center development is impacting the region and where future growth may be focused. In part one, we examine the continuing influx of new development in the region. Part two will examine the challenges of growth, and emerging controversies surrounding data center development.

There are at least seven new players planning to enter the Northern Virginia data center market in the next several years. The influx of real estate developers in the region is tied to investor interest in providing infrastructure for hyperscale operators in blue-chip markets.


In the data center world, Northern Virginia is the home of the cloud, housing the largest concentration of server farms for Amazon Web Services, Google, Microsoft and Facebook. This demand is particularly strong near a strategic Internet intersection in Ashburn, Virginia that serves as a global crossroads for data traffic. As the cloud grows, the ability to add servers near Ashburn has become the table stakes for companies with ambitions in cloud computing.

As a result, data center users seem to have an endless appetite for deploying servers in Northern Virginia. But how long can this boom continue?

In our DCF 2022 forecast, one of our predictions was that data centers will confront growing community resistance. This trend has emerged in a big way in Northern Virginia over the last month, as local officials in both Loudoun and Prince William counties have hotly debated the role of data centers in the local economy, and where these facilities should and should not go. Land speculation has driven up real estate values in both counties, but some new data center projects are meeting sharp resistance from local residents.

New Developments Fuel the Cloud Boom

In assessing the future course of the data center development in Northern Virginia, it’s important to understand the region’s current footprint, as well as the influx of new players and capacity.

Northern Virginia is home to about 250 data centers and the largest cloud cluster for Amazon Web Services, as well as major operations for Meta, Google and Microsoft. Loudoun County is home to 26 million square feet of existing data center space, with at least 8 million square feet in the pipeline. Prince William County reported more than 5 million square feet in its last update, and with recent development is likely in the range of 8 to 10 million square feet of data centers.

One might wonder whether there is room for more new developers, as the region is already the most competitive data center market. But in recent years Northern Virginia has absorbed the debut of five large providers – Cloud HQ, Aligned, Iron Mountain, Vantage Data Centers and QTS Data Centers – who have all experienced strong leasing. The region is also home to most of the major multi-tenant data center developers, with Digital Realty, Equinix, CyrusOne and NTT Global Data Centers having the largest presence.

Despite the large number of companies already serving the market, vacancy rates are near all-time lows at 3.6 percent, with many projects pre-leased prior to delivery. Many of the new entrants are privately-held operators backed by investors with ready access to capital.

Here’s a look at the new players entering the Northern Virginia market and the projects they have in the pipeline.
