NYU operates a CoGen plant under 251 Mercer that runs on natural gas and can fail over to diesel. It provides power, steam, and cold water for air conditioning to many of surrounding properties. The net result is that NYU servers frequently stay up during power outages, while their ISP usually goes down.
