The hacking group "Lizard Squad" took credit for the outages. The group previously claimed responsibility for cyber-attacks that briefly knocked the Vatican's website, and League of Legends offline.

Neither Microsoft nor Sony blamed the problem on hackers. Both companies said they were investigating the problems.

Earlier this month, the Lizard Squad claimed it hacked Sony's PlayStation Store.
