Digital Realty Trust, a leading global provider of data centre solutions, has signed an agreement with American Internet Services (AIS), a leading provider of enterprise-class data centre, cloud and connectivity services in the western United States, to expand its data centre presence in Digital Realty's 120 East Van Buren property in Phoenix, Arizona. 

AIS began its relationship with Digital Realty in November 2009 when opening its first premium data centre outside of the Southern California region. Phoenix was selected because of its reputation of being one of the safest locations in the nation in terms of protection from natural disasters. Digital Realty met AIS's requirements by delivering a state-of-the-art, concurrently maintainable facility designed for flexibility, reliability and efficiency that includes a 2N UPS configuration, N+1 cooling infrastructure and 24x7x365 onsite security/support personnel.
