I never said PSN was down at the moment. But the game being playable on the other platforms and not on playstation as nothing to do with PSN, wasn't the firmware 2.0 for PSN?
Maybe you'd prefer I used the "playstation infrastructure" terms?
It's cool that you're satisfied with the service but over the past few months I've been getting kicked out of Netflix sessions and had digital games locked cause the service crapped out so for a paying service I expect more, especially considering how many subs they got.
2.0 update has nothing to do with psn. Simply the update to the 2.0 update for the operating system of the PS4 has delayed the alpha for PS4.
