On Christmas Eve the Playstation network was offline and gamers were unable to log in to their PSN account. For a few hours gamers found it possible to once again log in and play their favorite online tiles for a brief time, but then once again was an able to log in. A hacker group called Lizard Squad took the credit for the attacks.
All through Christmas people who received a Ps4 would find that they were not able to play any online support for their games. Games like Destiny that do not offer an offline function could not be played at all during the attacks. Currently Xbox is online but PSN is still offline. The motivation for the attacks seem have been for Twitter folleres, Lizard Squad currently have 207k followers on Twitter.
