Update: The restriction to log in a few days before the maintenance has been lifted. As long as you have an active account with PSN as of the start of maintenance, you will be able to play online and access partner services such as Netflix while the maintenance is occurring. This is for PS4, PS3, and Vita platforms.
If you’ve been playing your PS4, PS3, or Vita over the last several weeks, then you’re more than aware of all the issues PSN has been having.
Sony has received a lot of hate due to the PlayStation Network being down for days over the holidays, and they continued to have several issues once PSN was back up and running again. Such issues have included messages not working right, downloads being slower than usual, the PlayStation Store taking forever to load, and some of us have even suffered from data corruption on the PS4.
Maintenance will begin at 9am PT/12pm EST
The PlayStation Network status page still shows a “Heavy Network Traffic” warning, and Sony announced earlier this morning that PSN maintenance will begin again on Thursday, January 15th. The maintenance is being done to add a series of back-end improvements to the network, and will begin at 9am PT/12pm ET.
During the maintenance period, the PlayStation Store, PlayStation Home, and Account Management will not be available; however, those who have logged onto the PlayStation Network any time prior to October 8th will be able to play games online and access partner apps, such as Netflix.
The maintenance will last approximately four hours, ending around 1pm PT/4pm ET, but there may be some additional downtime after the maintenance period for testing purposes.
