Super Bowl XLVII leaves its share of mysteries in its wake, and one of the biggest is unrelated to football tactics or the inner workings of the Harbaugh family: What caused the power outage just as the second half was getting started?

A power outage left the game in limbo for more than half an hour, baffling commentators and setting the stage for the dramatic near-comeback of the San Francisco 49ers.

Was it a ploy by Chinese hackers to exhibit their capabilities at a moment that had the attention of some 50 million Americans?

Did Beyoncé’s flashy halftime show overtax the Superdome’s circuitry?

The company Entergy, which supplies power to the Mercedes-Benz Superdome, says a sensor discovered an “abnormality” in the electrical load, triggering the shutdown.

“Shortly after the beginning of the second half of the Super Bowl in the Mercedes Benz Superdome, a piece of equipment that is designed to monitor electrical load sensed an abnormality in the system,” says a joint statement from Entergy and SMG, the management company for the Superdome.
