Electrical failure cuts power to all of Argentina and Uruguay, supplier says

I'm reading that the distribution sector is composed of two distribution companies (Edenor and Edesur).

Both websites are currently down:

www.edenor.com.ar www.edesur.com.ar

Be interested in technical reasons for this. Presumably those closest to it having a hard time getting on the net!

Too bad the electrical grid is so centralized.
