The power was out in various parts of East Boston this evening. It is back on for me, near the intersection of Bennington & Byron Streets, but I'm not sure if that is the case for everyone.
Earlier this evening, as I drove past the end of Lexington Street, near Day Square, I saw a firetruck, a police car and a small crowd. The power appeared to be out in that area, and I thought I saw a bit of smoke in the air. I'd guess there was a manhole fire, but I'm not sure.
My oven clock was blinking when I got home, so the power had been off, apparently briefly, and then it went off again from roughly 10 p.m. to 10:30. I found nothing about the outage on Boston.com, but Universal Hub has made reference to it.
