Looking @ that map; Canada, Africa, Russia and China don't have many YouTube users.
Or they were less affected because of the climate change, or their economy, or it's colder up North and warmer in Africa, or they are censored in China?
The top hackers in the world are from Russia, China and North Korea. ...The South too.
Canada doesn't have hackers, Canada has pot (marijuana)...legal too, not censored.
Saudi Arabia and China ... It's not their forte...free speech.
Africa? They have elephants, and safaris. ...High seas highjackers? ...They have deserts of sands.
Methinks it was an overload server data issue. Or, a diversion to take the world away from the latest news with Saudi Arabia. They have enough global control to buy this planet and sell it to the first alien bidder. Black gold can do that.
