"In the United States, the new Oak Brook facility complements AT&T's data center in nearby Lisle, Ill. to further expand the company's hosting presence in the Chicago area. The Oak Brook center's proximity to an AT&T central switching office means customers have convenient connectivity to the AT&T network backbone. In addition, the center maintains multiple active power and cooling distribution paths, redundant components and fault-tolerant design to provide 99.999 percent availability. As a result, the Oak Brook center has a Tier IV site infrastructure rating from the Uptime Institute -- its highest classification among data centers for reliability, availability and serviceability."
