After initially failing certification, the long-awaited PlayStation 4 version of Minecraft has launched today on the PlayStation Store. It's probably no coincidence that, not long after it went live, the PlayStation Network began experiencing a variety of issues.

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.

PSN was recently subjected to a DDoS attack that brought it down temporarily. After being brought back online, it again suffered from connectivity issues, though things have been working better since the end of August.

Minecraft is available on PS4 for $20, or just $5 if you own the PS3 version. This is the second time Minecraft has come to a PlayStation system, following last year's PS3 release. Despite being several years old at this point, Minecraft has been the top-selling PS3 game on the PlayStation Store every month since its release, and sales on other platforms have shown little sign of slowing. An Xbox One release is coming tomorrow, with a PlayStation Vita release still in the works.
