Hours after Microsoft’s Xbox Live went down Wednesday, Sony’s PlayStation Network went down, too.

These are two giant networks that console gamers access to play their games online. It's especially bad timing since a lot of people are probably getting new PlayStations and Xboxes for Christmas.

Since early Wednesday, the notorious hacker group “Lizard Squad” has claimed responsibility for taking down PlayStation Network on Twitter, saying it has downed both networks with denial of service attacks. That means the hacker group is flooding Sony and Microsoft's servers with bogus traffic.

Lizard Squad has been tweeting about these outages incessantly, boosting its number of Twitter followers by promising to restore the downed game networks if people favorite and retweet their messages a certain number of times.

As of Thursday afternoon, very little new is happening. It's an endless cycle: Lizard Squad claims it is DDoSing Xbox Live and PlayStation Network, it asks for retweets and favorites on Twitter to put the services back online, and those networks come back up for air only to get attacked again.

Sony’s “AskPlayStation” Twitter account has acknowledged the service issue, but has not stated whether or not it’s the result of a DDoS attack. Sony later tweeted that service was returning to normal, but we're still seeing a lot of complaints on Twitter. Xbox Live is still down.

Meanwhile, another hacker gang called “The Finest Squad” had apparently exposed several Lizard Squad identities online, and it also learned that Lizard was taking the big game networks using denial of service attacks.

“Lizard Squad” issued a threat last week saying it would take down the PlayStation and Xbox Live networks over Christmas.
