There are a number of data centers housed in the nearly 3 million square foot building that functions as a carrier hotel, a major connection point for hundreds of domestic and international telecommunications providers.

The building, along with all of lower Manhattan, has been on generator power since Con Edison cut service to the area Monday night because of floods caused by Hurricane Sandy.

The loss of power at multiple locations around lower Manhattan, including at 111 8th Ave.

uses some 26,500 square feet in the building, according to its Website. Thursday morning it published an "urgent communication regarding the status of the 111 8th Avenue facility."

The drama has unfolded, so far, in a series of three communications by Zayo to its customers with updates on the company's various efforts to address problems that have come as the data center temperature went up and down.
