The Telx Group was founded in 2000 based on the recognition that carriers at 60 Hudson Street in New York required an alternative to procuring local loops within the building for connectivity. In 2002, the company expanded within 60 Hudson Street from the 23rd floor to the 9th floor and by the middle of 2003 the company had over 100 customers in their 60 Hudson Street, NY Core Interconnection Facility.
Surviving the changes that underwent in the telecommunications industry in the early 2000's, Telx acquired the principal colocation center in Atlanta, GA located at 56 Marietta Street. Telx transformed the building into another Core Interconnection Facility by creating a "Meet Me Room" to facilitate customer interconnects. By the middle of 2004 the company had over 200 customers in two locations.
By the time GI Partners acquired The Telx Group in November 2006, the company had over 400 customers. In December 2006, Digital Realty Trust, owner and manager of technology-related real estate, and Telx entered into an agreement whereby Telx would now own and manage the interconnection facilities in ten Digital Realty Trust facilities in the United States. Keeping on our strategic path of becoming “The Interconnection Company” Telx acquired NYC Connect's interconnection suites at 111 8th Avenue, NYC in March of 2007.
In 2008 Telx continued to invest in expanding its core interconnection facilities into key markets by adding 70,000 square feet of new space in key markets including 8435 Stemmons Freeway in Dallas, and a premier colocation facility in Clifton, NJ.
In 2009, Telx was managing nearly 500, 000 square feet of space. Proving its solutions beneficial to the financial industry, Telx and ACTIV Financial partnered to offer highly secure, low-latency market data and colocation services, and ISE and Direct Edge announced the selection of Telx for Data Center services at 100 Delawanna Avenue, Clifton, NJ. In October 2009, Telx launched its Financial Business Exchange (FBX), a new exchange devoted to providing proximity to the interconnected capital markets community, through its data centers at 111 8th Avenue in New York City, 100 Delawanna Avenue in Clifton, N.J., 350 East Cermak Road in downtown Chicago, and 200 Paul Street in San Francisco.
Today, with numerous expansions within 15 facilities totaling 483,427 square feet, 800+ customers with over 28,200 Interconnections, Telx has solidified itself The Interconnection Company.
