A blackout across at least two countries.
Edesur, a major electricity provider in South America, has confirmed that the entire nations of Uruguay and Argentina have been left without electricity. The company is headquartered in the Argentinian capital of Buenos Aires.
The aggregate population of the two countries is over 48 million people. Certain parts of Brazil and Paraguay are also affected by the cut.
"A massive failure in the electrical interconnection system left all of Argentina and Uruguay without power," electricity supplier company Edesur said in a tweet.
The fault has coincided with a local election vote in Argentina, where it is currently mid-morning. Argentina Standard Time is four hours behind Dublin.
So far, the cause of the power failure is not clear, nor is there any indication for when the power will return. The effects on various elements of Argentinian and Uruguayan infrastructure - such as healthcare - remain to be seen.
