Puerto Rico suffered a major blackout Wednesday that snarled traffic, forced government offices to shut and left tourists stranded across the US commonwealth of 3.2 million people.

Puerto Rico Energy Czar Josue Colon said officials were still trying to determine what caused the problem but that it appeared a failure on a transmission line had triggered safety mechanisms that knocked all of the island’s power plants off line.
