Sony's PlayStation Online Network had an outage over the weekend, and just shut down for maintenance yesterday.

They posted on their forum saying: "We wanted to take a moment to inform you of a network maintenance, currently scheduled for Thursday, August 28th, Monday, August 25th, from 9:40 AM to 4:50 PM Pacific Time (12:40 PM to 7:50 PM Eastern Time). We expect this maintenance to last approximately 7 hours. During this time we will deploy a series of back-end improvements to the network."

They also indicated that users who have been having problems since August 23 will receive a maintenance notification, "We thank you for your patience and support and apologize for any inconvenience this may cause."

They started at 9:40 a.m. and worked with their servers until 4:50 p.m. yesterday.

However, while they are restructuring their systems, users can still play online games or even watch Netflix as long as they were signed into the network from the 23^rd of August.

Yesterday's maintenance was supposed to take place last Monday, but it was postponed after an unexpected cyber-attack on PSN last Sunday. It was reported that Lizard, a hacker group, was the one who took credit for the attack. The cyber-attack has affected Xbox Live, the PlayStation Network and other online game servers.
