An unprecedented blackout leaves the country without power and no explanations.

Catalonia went back centuries this Monday. Hundreds of people were trapped on trains and the metro—some for more than eight hours—and almost everyone was cut off, without internet or telephone access, all day. Cooking hot food was almost impossible, as was paying by card, and most businesses had to close their doors. A general power outage has paralyzed the country, including Spain and Portugal, and the incident has still not been fully resolved. There have also been no conclusive explanations.
