CoreSite Realty is a data center REIT with a focus on network dense buildings. The company operates the Any2 Peering Exchange, which is the largest Internet Exchange in the Western US.
CoreSite History
CoreSite Realty Corporation was founded in 2001 as CRG West, a portfolio company of The Carlyle Group. CRG West initially started with two data center buildings; One Wilshire in Los Angeles and 55 South Market in San Jose. The buildings were popular network interconnection and peering points. Although 55 S Market has declined as an interconnection point, One Wilshire continues to be a popular building for network interconnection.
2007: Sold the Company's Jewel to Fuel Expansion
In August, the company sold the One Wilshire Building to Hines REIT for $287 million. The large transaction gave CRG West additional capital to fund the company's growth into new markets.
In May, CRG West acquires buildings in Chicago (for $34 million) and Sommerville just outside of Boston. The Chicago building at 427 S LaSalle was originally designed and built by Western Union. Western Union buildings have traditionally been converted into Carrier Hotels because the telegraph infrastructure with their risers of conduits works well for the telecom industry. The facility is situated across from One Financial Plaza and adjacent to the Chicago Board of Trade.
CoreSite Boston at 70 Innerbelt Road, Somerville, MA is located less than two miles from downtown Boston and Cambridge. The large building has SunGard and Internap as significant tenants also offering colocation
2008: Added Reston
CRG West acquired their Reston facility at 12100 Sunrise Valley.
2009: Rebranded
CRG West rebranded as CoreSite.
2010: IPO added More Capital to Expand
In September, CoreSite became publicly traded on the New York Stock Exchange (NYSE: COR). The Carlyle Group still owned ~50% of the newly public company at the time of the IPO. The Carlyle Group has since reduced their ownership to less than 30%.
2012 Added Denver
In April, CoreSite acquired Comfluent and their two Denver data centers. The data centers were small, but pivotal to the Denver Interconnection and Peering Market. DE1 is located in 910 15th Street, Denver's Telecom Hotel, the Denver Gas & Electric Building (DGEB.) Comfluent was the defacto meet me room for the building. DE2 was 639 E 18th Ave, which was adjacent to Level 3's Denver Gateway site.

Reston Campus Expansions
12100 Sunrise Valley was first acquired in 2008 and CoreSite has since turned the Reston site into a campus. The company constructed a building (VA2) in the parking lot. In 2018, Coresite acquired a 22-acre lot a few blocks away at 12379 Sunrise Valley Drive. The lot will serve to virtually expand the Reston Campus.
