Who We Are Is at the Heart of Everything We Do

Simple. Honest. Strong. This is the motto on which CoreSite was built, and the words that our employees live by every day. For our customers, these core values translate into employees who are willing to go beyond the norm to provide exceptional customer service, and data center solutions that are built with our customer’s individual business needs in mind. CoreSite data centers are some of the best in the colocation industry, in part because we take pride in applying our simple, honest, strong motto to the way we do business.

A History to Build Upon

CoreSite, an American Tower company started in 2001 as CRG West, a portfolio company of The Carlyle Group. It was created to meet the needs of interconnection and data center customers at One Wilshire in Los Angeles and 55 South Market in San Jose.

Strategic Growth

From 2001 through 2009, CRG West continued to expand its data center footprint across the U.S. and broaden its offering of interconnection services. As CRG West's strengths and abilities continued to grow, so did the company's customer base. The Any2Exchange® for Internet peering was launched and quickly became the second largest of its kind in the country.

Positioned for Success

In 2009, CRG West rebranded as CoreSite—a name more indicative of the company’s national capabilities, international reach and mission-critical reliability. In 2010, CoreSite became publicly traded on the New York Stock Exchange (NYSE: COR). Today, CoreSite has 28 operational data centers in ten major communications markets across the United States, serves more than 1,375+ customers and has a portfolio totaling more than 4.7 million square feet of data center space.

“We’ve been with CoreSite for nearly seven years and the reason we keep choosing CoreSite solutions is because no other vendor can provide the same combination of world-class technologies, high-touch customer service, and 100% uptime. It truly is the gold standard for data centers in our industry.”
