Our Hosting FacilitiesServers

Server cages at the CR hosting facilities ClassroomRevolution.com provides world-class hosting services using servers housed at three state-of-the-art data centers in Dallas, Texas. Each location offers complete redundancy in power, HVAC, fire suppression, network connectivity, and security. With over 83,000 sq ft of raised floor between the three facilities, our datacenter facility sits atop multiple power grids driven by TXU electric, with PowerWare UPS battery backup power and dual diesel generators onsite. Our HVAC systems are condenser units by Data Aire to provide redundancy in cooling coupled with ten managed backbone providers. Twelve more third party backbone providers are available in the building via cross connect. Fire suppression includes a pre-action dry pipe system including VESDA (Very Early Smoke Detection Apparatus) with over 700 smoke detectors between the two facilities.
