Digital Realty has announced it has achieved "five nines" of uptime for the 12th consecutive year, exceeding 99.999 percent availability throughout 2018.

"Delivering 'five nines' of uptime for the 12th straight year demonstrates our commitment to resiliency and to serving as a true business partner to all our customers, from enterprises to telecommunications customers to leading cloud service providers," said A. William Stein, chief executive officer, Digital Realty. "We are especially proud of this milestone given our rapid growth, and we remain focused on ensuring that all of our facilities around the world meet the same rigorous standards for design, construction and operations."

Digital Realty recently surpassed 2.1 billion operating minutes across its 214 data centers, encompassing approximately 30 million square feet across 35 metropolitan areas globally. Over the past 12 years, the number of data center suites operated by Digital Realty has grown from 74 suites at the start of 2007 to more than 800 by the end of 2018.

"I am proud of our industry record on resiliency, which serves as the bedrock for all of our offerings, from interconnected scale, with options ranging from a single rack up to multiple megawatts, to the ability to connect directly, privately and securely to any combination of public, private and hybrid cloud offerings," said Erich Sanchack, executive vice president, operations, Digital Realty.

Uptime metrics are based on a comprehensive evaluation of data center suites owned and operated by Digital Realty worldwide, using standard industry methodology. Total operational minutes were prorated per year for each data center suite, beginning on the commissioning date, from the start of 2007 through 2018.
