Shortly past midnight, U.S. Pacific Time, Sony announced that PlayStation Network service had been restored in Canada, all 50 U.S. states and Puerto Rico. PSN, down for 22 days following a massive cyberattack on April 19, continues to be restored in stages in Europe and in other regions.

Sony Online Entertainment, the publisher of PC MMO titles also shut down by April's massive cyberattack on the PlayStation Network, has also begun the reactivation of its network services, according to a statement by SOE.

PlayStation Network, down since April 20, will return this week, said Kazuo Hirai, the second-in-command for Sony Corp., at a news conference today in Tokyo.
