Around 48 million people in Argentina and Uruguay were affected by a massive electrical failure at the weekend which caused trains to be halted and with traffic lights to fail. This was a total power failure and not just semi isolated incidents and could have come at a worse time given that people in Argentina were preparing to go to the polls for local elections. The only blessing was that it was on a Sunday which is traditionally a quieter day. Had it been during the working week there would have been chaos.
Although Argentina & Uruguay were the worst affected, parts of Paraguay and Chile were also hit.
What Caused The Blackout?
According to Edesur the electricity supply company responsible, it was a massive failure that occurred in the interconnection system.
📣 Para garantizar la reposición total del servicio seguimos trabajando en la solución de casos puntuales que se desprenden de la falla masiva ocurrida en el sistema de interconexión.

Other sources seem to indicate that it also involved a transmission failing at the Yacycretá hydroelectric dam. What is clear so far is that there is no definite answer and the possibility of a cyber attack hasn’t been completely ruled out.
