PlayStation users are experiencing connectivity issues with the PlayStation Network which is keeping some from logging into the service, Sony confirmed early this morning.
In a statement on the official PlayStation Twitter account, it was confirmed engineers are currently on the case and investigating the problem. Likewise, Sony's PSN support page shows that the service is currently experiencing heavy network traffic.
This is a continuation of problems surrounding PSN since Christmas. Two groups of self-described hackers have been fighting over a threat to take down both the PlayStation Network and Xbox Live on Christmas Day. Lizard Squad, a group that claims responsibility for previous network outages and diverting Sony Online Entertainment head John Smedley's flight in August, also promised to launch the Christmas Day attack.
On Twitter, Lizard Squad previously claimed credit for the downtime on both PSN and Xbox Live last year.
