I've just read about it. It seems it hit Portugal, Spain and France. Damn...stay safe:
from the second link:
"At least an hour after the outage, authorities were still unable to explain the cause, though they did not rule out the possibility of a cyber attack. Investigations into the incident are ongoing, and a crisis committee was set up in Spain to manage the situation. Emergency cabinet meetings were convened by both the Spanish and Portuguese governments, and the blackout briefly affected parts of France near the Spanish border.
Portugal’s utility company REN confirmed that the power cut impacted the entire Iberian Peninsula, including parts of France. Red Electrica in Spain is working closely with regional energy companies to restore power, and REN stated that plans for phased restoration were being activated in coordination with European energy producers and operators."
