Each data center is protected by an uninterruptible power supply (UPS), which provides backup battery power in the event of a power outage and regulates utility power fluctuations that might damage your server. Data centers have backup diesel generators that will take over power production during extended outages. Power distribution in the data center has multiple layers of redundant components to help prevent power loss to your server in the event of a hardware failure. The UPS and generator are serviced regularly by certified staff, stopping problems before they start, and are also monitored 24 hours a day, seven days a week.
