In 2009, CRG West rebranded as CoreSite – a name indicative of the company’s capabilities, international reach and mission-critical reliability. At that time, CoreSite had 11 data centers in seven markets, recognized the importance of customer experience and that providing retail and wholesale scale colocation created value for a broad set of customers.
