Supporting performance-sensitive customer requirements with industry-leading reliability

DENVER--(BUSINESS WIRE)--Jan. 7, 2016-- CoreSite Realty Corporation (NYSE:COR), a premier provider of secure, reliable, high-performance cloud-enabled data center solutions across the U.S., today announced that for the fifth consecutive year it has achieved portfolio-wide uptime exceeding 99.9999 percent, or “six 9s”, across its platform of data center facilities.

CoreSite’s high-availability data centers ensure an industry-leading level of operational performance, with six 9s availability being equivalent to unscheduled downtime of less than 32 seconds per year against CoreSite’s 100 percent uptime service level agreement. By contrast, five 9s uptime correlates to downtime exceeding five minutes annually. When compared to five 9s, six 9s availability provides businesses with nearly 10 times the statistical reliability in the data center environment. Operating at such a high level of availability and reliability is paramount in today’s high-tech marketplace, underscoring the critical importance of enabling information and communications technology capabilities.

“We are once again pleased that our focus on operational excellence and the professionalism of our Field Operations organization has resulted in our achievement of six 9s uptime across our national platform of highly connected, cloud-enabled, enterprise-class data centers,” said Tom Ray, CEO at CoreSite. “We take pride in delivering high-performance data center and interconnection solutions, all supported by best-in-class customer service, to enable business performance.”

The reliability of CoreSite data centers hinges on maintaining strict standards of excellence for the company’s Facilities and Field Operations team. CoreSite’s related on-site professionals undergo rigorous internal training and recurring exams that each professional must pass to reach specified levels of accountability. CoreSite’s platform is validated across numerous compliance regimes, including PCI, DSS, and SSAE 16 SOC 1 and SOC 2 Type 2; additionally, CoreSite has attained the International Organization for Standardization certification (ISO 27001) covering both its corporate policies and procedures as well as those of all of its operating data centers. Together these attestations provide customers with an additional, third-party review of the reliability of CoreSite’s professionals, infrastructure and systems.
