A power outage left much of the campus without electricity Thursday night. Parts of upper campus-including the Goldfarb Library and the Usdan Student Center-were without power from around 11:30 p.m. to 5:30 a.m. Friday, said Joseph Castronovo, the electrical supervisor for Facilities Services.The cause of the blackout is still under investigation, Castronovo said, but the problem involved some of the University's new electrical equipment.

In a campuswide e-mail, Chief Operating Officer Peter French said off-campus work done Thursday by the electric company NStar may have triggered the power surge that disrupted the campus electrical network.

Electricity was also lost in the Science Complex, North Academic Quad, North Residence Quad, Kutz, Goldfarb, Rosenthal, Massell, the Administrative Complex, Sherman and the Faculty Center, according to French. The campus' computer and phone systems remained operational during the blackout, he said.
