WTOP is reporting that the Capitol has been evacuated following a loss of power. No word on the return of utilities at this point. Got a tip for us? Drop a comment.

Update

Well, Power’s back on now, after 90 minutes of work:

Mary-Beth Hutchinson, a spokeswoman for Potomac Electric Power Co., said the electricity was shut off automatically after there was “a momentary drop in voltage due to customer operations up the lines” away from the Capitol.

“The protective equipment sensed the significant change in voltage and tripped,” she said.

Whoever it was that decided to fire up that new supercomputer cluster….oops.
