We wanted to take a moment to inform you of a planned network maintenance, currently scheduled for Monday, January 27th from 9:30 AM to 3:30 PM Pacific Time (12:30 PM to 6:30 PM Eastern Time). We expect this maintenance to last approximately 6 hours.
If you’ve signed in to PlayStation Network any time since January 20th you will be able to play games online and access partner apps such as Netflix during this maintenance period. The PlayStation Store, PlayStation Home and Account Management will not be available during this time, and users may receive a maintenance notification when attempting to access these services.
We thank you for your patience and support and apologize for any inconvenience this may cause. In order to access online game play and partner apps during this routine maintenance, we ask that you please sign in to PlayStation Network prior to Monday, January 27th.
[UPDATE] If you are having issues signing in to Netflix, please see this thread for help: http://community.us.playstation.com/t5/PlayStation
