Sony has announced that PSN (PlayStation Network) is back online after a massive network attack over the weekend:

The PlayStation Network and Sony Entertainment Network are back online and people can now enjoy the services on their PlayStation devices. The networks were taken offline due to a distributed denial of service attack. We have seen no evidence of any intrusion to the network and no evidence of any unauthorized access to users’ personal information.

In light of today’s issue, the networks will not undergo the regularly scheduled maintenance, which was planned for Monday, August 25. We will provide an update shortly for when the maintenance will be rescheduled.

We sincerely apologize for the inconvenience caused by this issue. Thanks for your patience and support.

***

Like other major networks around the world, the PlayStation Network and Sony Entertainment Network have been impacted by an attempt to overwhelm our network with artificially high traffic.

Although this has impacted your ability to access our network and enjoy our services, no personal information has been accessed.

We will continue to work towards fixing this issue and hope to have our services up and running as soon as possible.

We regret any inconvenience this may have caused.
