The NDP will return to work within a couple of days?

The attack was more serious than initially revealed an anonymous source close to Sony said that the attack on the PlayStation Network could be more serious than reported, since this was an attack carried out with LOIC capable of damaging the server . At the same time there was an attack on the servers that store the information of the PSN account, and finally were violated admin accounts.

As a result, in the sight of all was the "off" of the NDP to restore the backup on new server, with new accounts to admin. The good news is that the backup and recovery should be completed in time to restore service within a couple of days, perhaps as early as tomorrow for the U.S. PSN.
