Sony has blamed distributed-denial-of-service (DDoS) attackers for causing PlayStation's network to go titsup on Christmas Day.
The Japanese firm struggled for nearly three days to restore services, following an assault on its PSN login system.
Microsoft's Xbox Live also suffered a DDoS attack on 25 December. But that service recovered not long after rotund file-sharing baron Kim Dotcom apparently convinced the wrongdoers to stop disrupting the services.
He offered a sweetener to a collective known as the Lizard Squad, which had claimed to be behind the coordinated, festive strike on gaming giants.
Sony said late on Saturday night:
PlayStation Network is back online. As you probably know, PlayStation Network and some other gaming services were attacked over the holidays with artificially high levels of traffic designed to disrupt connectivity and online gameplay. This may have prevented your access to the network and its services over the last few days.
Thanks again for your support and patience.
