Sorry, Xbox Live profiles can’t be downloaded right now. Please try again later.
Hacker group Lizard Squad, famous for its distributed denial-of-service (DDoS) attacks, took responsibility for the attack on Twitter yesterday.
Lizard Squad was also responsible for taking down Destiny and Call of Duty: Ghosts, FIFA, Madden and Sims 4 earlier this year. They also made bomb threats against Sony Online Entertainment President John Smedley. The group had announced that they would be disbanding because several of their members were caught by the FBI, but it looks like they are back.
All that can be done now is to wait and see what Lizard Squad can do.
Xbox Live was experiencing log-in issues for some Xbox 360 and Xbox One customers. Service has since been restored-customers now have full access to Xbox Live. As always, please refer to our Xbox Support page for the latest status updates.
We do not comment on the root cause of a specific issue.
