The team is hard at work on fixing these known issues, and users may see a few maintenance notifications when they log on. With Sony aware of what's going on and many players aiding in being able to nail down which parts are being derailed, the anticipated fix should be up shortly.
Update:
Many users are now reporting that the PlayStation Store and PlayStation Vue features are back up and running. More fixes to follow.
voila, bref beaucoup de problèmes mais SOny est au courant et travaille a réparer ça
