Users on Twitter and NeoGAF are reporting they are having issues when attempting to connect to PSN; this includes receiving the error code NP-36147-1. I, for one, can't do anything involving PSN, such as viewing my friends list or accessing the PlayStation Store.
The official Twitter support account for Twitter has confirmed the issues. "We are aware that there are currently some issues with accessing PSN," a tweet sent out this afternoon reads. "Thanks for your patience as we work to resolve the issues."
Another tweet acknowledges issues involving Minecraft for PS4, but doesn't outright connect its launch to the PSN problems. "If you are having issues getting or accessing Minecraft for the PS4, please try again later," it advises. "We are looking into the issues."
We've contacted Sony to find out more and will report back with anything we learn.
