It turned out to be from a manhole explosion in the street nearby and NStar was called in.

Witnesses say the manhole cover flew about ten feet in the air.

According to the fire department on Twitter, the conditions in the manhole worsened and power had to be shut off to the entire building, which has a Starbucks and FedEx office on the first floor.
