A massive blackout affected hundreds of thousands of users Saturday night in neighborhoods of Buenos Aires, causing traffic light failures and leaving people trapped in elevators, requiring the intervention of firefighters of the Argentinian capital.

At its peak at 9:45 p.m. local time, the outage reached 519,472 users of Edenor and 78,125 of Edesur, according to reports from the National Electricity Regulatory Entity (ENRE). Within Edesur’s concession area, the hardest-hit zones included La Paternal, Flores, Floresta, Villa del Parque, Vélez Sarsfield, Caballito and Villa Santa Rita, with outages also reported in Palermo, Belgrano, Villa Urquiza and Villa Devoto.
