Dulles Technology Corridor

The Dulles Technology Corridor is a business cluster containing many defense and technology companies, located in Northern Virginia near Washington Dulles International Airport. The area was called "The Silicon Valley of the East" by Atlantic magazine. It was dubbed the "Netplex" in a 1993 article by Fortune magazine. Another article in 2000 claimed that the area contained "vital electronic pathways that carry more than half of all traffic on the Internet. The region is home to more telecom and satellite companies than any other place on earth."

The Dulles Technology Corridor is a descriptive term for a string of communities that lie along and between Virginia State Route 267 (the Dulles Toll Road and Dulles Greenway), and Virginia State Route 7 (Leesburg Pike and Harry Byrd Highway). It especially includes the communities, from east to west, of Tysons Corner, Reston, Herndon, Sterling, and Ashburn. These communities are in Fairfax and Loudoun counties, which are the second-highest and highest income counties in the U.S. as of 2011, coinciding with the national technology and local internet boom of the 1990s and local technology spending after the September 11, 2001 attacks.

As of 2009, greater than 50% of all U.S. Internet traffic travelled through Northern Virginia. In 2013, as much as 70% of the world's Internet traffic travelled through data centers in Loudoun County. In his book Tubes, author Andrew Blum calls Ashburn, Virginia—a community within the Dulles Technology Corridor—"the bullseye of America's Internet". The Dulles Technology Corridor serves as headquarters for domain name registrar Network Solutions and network infrastructure company Verisign. The region contains the Internet Society, and used to contain the mainframe that houses the master list of all Internet domain names.
