(Malaysian's, correct me if I'm wrong here)
The last major blackout in my country was a horrible one, I think it happened 4-5 years ago.
The whole country's electricity supply went out for more than 24 hours.
The entire country was completely crippled when this unexpected incident came about.
Unlike Jari's case it wasn't caused by some natural disaster or something.
IIRC, one of the main power generators blew causing some kind of chain reaction taking every other power generator's connected to the main grid, even the backup ones. Talk about catastrophe...
