Part of which is also known as the Dulles technology corridor, it is a quiet affluent business cluster that stretches from Tysons to Loudoun County in Northern Virginia, U.S..
In a few decades, most notably after the internet comes to existence, the corridor has grown from a sleepy residential area to a prosperous business district, and largely been left out of the bar and restaurant boom that helped turn downtown Washington into a destination for young professionals.
With a full-fledged service economy, it becomes a home to world headquarters for several internet-related and high tech companies.
The area 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 considered 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.
As of 2009, it was said that more than 50 percent of U.S. internet traffic was processed in this Northern Virginia area. And as of 2013, it grew to pass as much as 70 percent of the world's internet traffic which traveled through its various data centers.
At the time, this translates to about 2.2 million terabytes of data every single day.
The Dulles technology corridor also includes Virginia's "Data Center Alley", which was considered as an area that quickly emerged as a national hub for data storage facilities.
This can be seen with the many massive, windowless buildings that stood up on empty fields, with large, exterior power systems.
The area was once called "The Silicon Valley of the East", dubbed the "Netplex", and claimed to contained "vital electronic pathways that carry more than half of all traffic on the internet.
The region is also said to home "more telecom and satellite companies than any other place on Earth," and also stated as "the bullseye of America's Internet"
One of reasons for the area becoming popular among tech companies is that because it has some of the country's cheapest electricity rates.
As of 2016, Loudoun is home to more than 60 data centers that house some 3,000 technology companies. Equinix alone has 11 centers in the county.
It was said that if an internet service went offline, something should have gone wrong in this Northern Virginia area.
The companies which have major regional offices located in the Dulles Technology Corridor, include: Amazon, Airbus, AOL, Apple, Boeing, Cisco Systems, DELL, Google, Hewlett-Packard, IBM, Microsoft, NEC, NetApp, Oracle Corporation, Palo Alto Networks, Salesforce, Symantec, Unisys, Visa, Verizon and more.
