Somebody fumbled big time during last night’s Super Bowl.

The power at the New Orleans Superdome went out at the start of the second half of the big game — bringing a sporting event watched by some 100 million people to a screeching halt for more than 30 minutes.

The embarrassing electrical debacle bathed the field in darkness, as half the lights went out about 1 1/2 minutes into the third quarter. It also led to finger-pointing between the NFL and New Orleans power officials.

League officials blamed the surge on something “outside the field coming into the stadium,” but the local power supplier thought differently.

The energy company Entergy New Orleans threw the yellow flag back at the football league and the Superdome, tweeting: “Power issue at the Super Dome appears to be in the customer’s side. At all times, our distribution & transmission feeders were serving Superdome.”
