“We are currently investigating, and working to resolve this issue as soon as possible,” the alert reads.

University spokeswoman Maralee Csellar said service was restored to all buildings except Alumni House, where the Office of Alumni Relations is housed, by 10:30 a.m. and she attributed the service interruption to “an unforeseen technical issue.”

“Service was interrupted because of an unforeseen technical issue. As soon as we identified the issue, technicians worked quickly to restore service. By 10:30 a.m. all buildings but the Alumni House were operational, with Alumni House expected to have full service restored by early afternoon,” she said.
