Overview
Quality Technology Services, commonly known as QTS or QTS Data Centers, is an American data-center infrastructure company headquartered in Overland Park, Kansas. It operates carrier-neutral facilities that provide colocation, interconnection, network access, infrastructure support, and related services to enterprises, telecommunications providers, cloud platforms, government customers, and other organizations that require secure and scalable computing environments. The company began in 2003 when Chad Williams acquired a data center in Kansas. It subsequently pursued an acquisition-led expansion strategy, adding facilities, customer portfolios, hosting operations, and development sites across the United States. Early transactions included the purchase of Deltacom's e^deltacom business unit and a Suwanee, Georgia data center in 2005, followed by acquisitions involving facilities and hosting businesses in Atlanta, New York, Silicon Valley, and other markets. These transactions helped QTS build a geographically distributed platform rather than relying on a single metropolitan location. A major part of QTS's development strategy has been the conversion and expansion of large industrial or technology properties into data-center campuses. In 2010, it acquired the former Qimonda semiconductor site in Richmond, Virginia, and developed it into a large-scale facility. The Richmond site also became a network access point for subsea cable systems terminating in the region. QTS later added properties in Kansas, San Francisco, Texas, Chicago, New Jersey, Atlanta, the Netherlands, and other markets. Its portfolio is concentrated in major connectivity and technology hubs including Northern Virginia, Dallas/Fort Worth, Chicago, Hillsboro, Oregon, New Jersey, Atlanta, and Richmond. QTS became a public company through an initial public offering in 2013. During its public-company period, it continued to expand through acquisitions, including Carpathia Hosting in 2015 and a New Jersey data-center campus acquired from DuPont Fabros Technology in 2016. In 2021, companies affiliated with Blackstone agreed to acquire QTS for approximately $10 billion, with the transaction completed on August 31 of that year. The acquisition returned the company to private ownership and placed it within Blackstone's infrastructure and real-estate investment ecosystem. Environmental performance has been a visible part of QTS's corporate positioning. World Finance Magazine named the company the most sustainable company in the data-center industry in both 2019 and 2020. QTS is also associated with RE100, a corporate initiative focused on sourcing electricity from renewable sources. The company has announced renewable-energy-powered facilities and has developed projects intended to operate with renewable electricity, including its Hillsboro, Oregon campus. It has also described partnerships and environmental initiatives involving American Forests and World Vision. QTS operates data centers across numerous U.S. states and in the Netherlands, with a further United Kingdom development planned at Cambois in Northumberland. In 2025, Chad Williams announced that he would leave the chief executive and chairman roles and return to Quality Group of Companies, the family-office and business-services organization from which QTS originated. David Robey and Tag Greason were appointed co-chief executive officers. QTS remains an active operator focused on large-scale, carrier-neutral data-center campuses and digital infrastructure capacity.
History
Quality Technology Services was founded in 2003 by Chad Williams after he acquired a data center in Kansas. The business expanded rapidly through a combination of acquisitions and development of large campuses. In 2005, QTS acquired Deltacom's e^deltacom business unit and its Suwanee, Georgia data center. The following year, it acquired a large Atlanta data center, Globix Hosting LLC, and NTT USA LLC, which owned a facility in the New York metropolitan area. In 2007, QTS acquired customers from First National Technology Solutions and added data-center and office technology space in Silicon Valley. It expanded into Florida in 2008. In 2010, QTS purchased the former Qimonda semiconductor property in Richmond, Virginia. The company converted the site into a roughly 1.3-million-square-foot mega data center. The Richmond facility later became associated with the QTS Richmond Network Access Point, where subsea cable systems including MAREA and BRUSA terminate. QTS added another Kansas facility in 2011 and expanded on the West Coast and in Texas in 2013 through the acquisition of Herakles LLC and its San Francisco data center and the purchase of land in Irving for a planned facility. QTS entered the public markets in October 2013 through an initial public offering. It acquired the former Chicago Sun-Times plant in 2014 with plans to convert the property into a data center. In 2015, the acquisition of Carpathia Hosting for $326 million broadened the company's hosting and managed-infrastructure capabilities. In 2016, QTS acquired a New Jersey data-center campus from DuPont Fabros Technology for $125 million. Further Texas and Atlanta expansion followed in 2017. The company expanded internationally in 2019 by acquiring data centers in Groningen and Eemshaven in the Netherlands for $44 million. That year and the next, QTS received recognition from World Finance Magazine as the data-center industry's most sustainable company. In late 2019 it announced an Atlanta campus expansion adding more than 250,000 square feet of leasable capacity, with development completed in 2020. QTS also began development of a greenfield campus in Hillsboro, Oregon, designed to operate with renewable energy. QTS's sustainability program became an important part of its corporate identity. It joined RE100 and reported renewable-energy use across multiple facilities. In 2020, it described environmental and social initiatives involving American Forests and World Vision. By 2021, the company stated that eight facilities used renewable energy for operations. Blackstone Infrastructure Partners and Blackstone's non-traded real-estate investment trust, BREIT, agreed in 2021 to acquire QTS at $78 per share. The transaction was completed on August 31, 2021, for approximately $10 billion, making QTS a private company under Blackstone-affiliated ownership. In 2025, Chad Williams stepped down from his QTS leadership positions and returned to Quality Group of Companies, the diversified real-estate and business-services family office from which QTS had originated. David Robey and Tag Greason became co-chief executive officers. QTS also announced a planned data-center development in Cambois, Northumberland, United Kingdom, with an initial phase targeted for 2026 and full construction planned through 2035. The same year, the company faced local criticism in Fayette County, Georgia, after an investigation found undisclosed water connections associated with a facility. Reports said approximately 30 million gallons had been drained and that QTS paid $150,000 in retroactive fees, while the incident occurred amid drought-related requests for residents to reduce water consumption.
