The PlayStation Network will be down for maintenance tomorrow, Thursday Nov. 17th, from 8 AM until 10 PM Pacific time. You won’t be able to access the PlayStation network during the scheduled 10 hours maintenance, but if you sign in before down time then you might still have a chance to save your Thursday night online gaming session. Sony will be using this time to introduce the new game sharing restrictions, which will limit your purchased content from the PlayStation Store to two PS3 systems or two PSPs. Fore more information on the new Sharing restrictions, refer to Eddie’s post.
