PlayStation Network down for maintenance next week
On the PSN Service Status page, Sony says that maintenance will begin at 5.30am on May 25 and last for two hours. It adds that you’ll still be able to log into your PSN profile, play games, and “use most applications while this maintenance is carried out.”
However, it says that you will not be able to access Account Management, PlayStation Video, and PlayStation Store during this maintenance.
"We strive to ensure that PlayStation Network services are available at all times, but occasionally we must take PlayStation Network offline to perform essential maintenance and implement feature enhancements. We are working hard to reduce the duration of each maintenance. We apologize for any inconvenience," it wrote.
