In light of yesterday’s DDOS attack on various Sony services including the PlayStation Network and Sony Entertainment Network, Sony had decided to postpone today’s planned PSN maintenance.

News of the postponement was made available earlier today on the PlayStation Blog:

UPDATE: 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 unauthorised 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, 25th August. We will provide an update shortly for when the maintenance will be rescheduled.

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

This announcement will likely come as some much needed good news for all PlayStation users.
