Well, it's that time again when Sony brings down PlayStation Network for scheduled maintenance. Don't worry, it's only supposed to last six hours. Of course, as most PlayStation gamers are aware, a six hour maintenance period can sometimes turn into 24 hours (or more) of downtime.
The maintenance is planned for tomorrow, Wednesday, September 25th from 9:15am to 3:15pm Pacific Time (12:15pm to 6:15pm Eastern).
As usual, if you've signed onto PSN over the past few days, you'll still be able to play online and access apps during this period; however, you may receive a maintenance notification when attempting to access the PlayStation Store, PS Home, and Account Management. So if you want to play games online tomorrow be sure to sign in before maintenance begins.
