Sony have announced that the PlayStation Network will be undergoing maintenance this Wednesday, 25th September 2013, with the downtime affecting your evening gaming session. The PlayStation Network will be offline between 3:00 PM until 3:00 AM on Thursday, 16th September 2013.
The PlayStation Store update usually takes place on Wednesday evenings too, so you won’t be able to download any new content until the maintenance is complete. For the duration of the maintenance you will be unable to log into the PlayStation Network, Account Management and the PS Store. PS Home will also be unavailable. Sony also say there may be some additional downtime after the maintenance period for testing purposes.
