Zayo is posting all of its .

In its first missive, Zayo told its customers that the temperature in one of its data center suites had reached 93 degrees. The company blamed "technical difficulties with the fuel pumping system to a subset of generators within the building, affecting the AC power."

In a later notice, published early this afternoon, Zayo said that temperatures in parts of the data center "have risen above 100 degrees."

It followed that with a note published after 2 p.m. Thursday reporting that the generator serving its data center suite "was taken off-line to implement a temporary fix." Workers hoped to stabilize the fuel pump and flow to the generator "in an attempt to return portion of cooling online," the note said.

In its latest posting, the data center operator said, "All Zayo network and customer equipment successfully transitioned to Zayo's DC battery plant with no interruption to customers. Zayo's DC plant provides for an estimated 5 hours run-time should the generator have to be taken off-line for maintenance or if there should be a failure.
