Northern Virginia is the largest market for data center space in the U.S., home to 4.6 million square feet (SF) of commissioned data center space, representing 616 megawatts (MW) of commissioned power, according to market research from datacenterHawk. Northern Virginia is one of the primary battlegrounds in the cloud war. It’s of major strategic importance to Amazon Web Services (AWS), whose Amazon US East region spans more than 25 data centers across Loudoun and Prince William counties. It looks like Amazon Web Services is continuing its relentless expansion in Northern Virginia. The cloud computing titan’s primary landlord in the region, Corporate Office Properties Trust (COPT), is building two new buildings in Ashburn that are fully leased to an unnamed “investment grade Fortune 500 company.” The property, known as ParagonPark, is an undeveloped parcel along Route 28, about a mile from the newest cloud campus for Amazon Web Services (AWS). Documents filed with Loudoun County indicate the site will house two data centers, while COPT said both structures will be 148,600 square feet – the same size as multiple data centers it has built for AWS in Northern Virginia.
