WASHINGTON (Reuters) - A power failure hit the U.S. State Department on Monday but telephone service and the building's operations center were working again by mid-morning, a department official said.
Internet service was disrupted by the outage. No further details were available and the State Department official said the authorities were looking into what caused the power failure.
The department said last month its unclassified email systems were hit by a cyber attack but there was no early indication the outage was related to a breach.
