Sony's online PlayStation store wasn't available to users for part of Monday in what seems to be a hack attack. The gaming network and the PlayStation Store were both kicked offline and Lizard Squad is claiming responsibility this time.
Sony has revealed little information about what happened so far, but it's clear the outage wasn't a result of routine maintenance.
Lizard Squad sent out a tweet with a clear message last night.

Earlier this year, Lizard Squad warned that explosives might be on a flight that included a Sony executive among its passengers. American Airlines was forced to divert the domestic U.S. flight to a nearby airport. For that incident, hackers orchestrated a denial-of-service attack against Sony, which involved overwhelming the company's game network with fake visits so legitimate users couldn't get through.
The electronics and entertainment company said the issue lasted two hours but has been fixed worldwide. The cause is still under investigation but there is no sign of any material being stolen.

Sony has had a hard time lately preventing attacks. Prior to the network problems, the company was the subject of a number of high profile movie leaks and employee details were also leaked following a recent attack.
Sony sent out a tweet acknowledging the connection issues, saying that the problems were being "looked into."
The PS Store also rendered inaccessible, though it isn't clear whether the two problems are related. Users visiting the Store currently are met with a message that reads: "Page Not Found! It's not you. It's the Internet's fault."
At the moment it appears that the PlayStation Network is back up and running, but for some the PlayStation store still shows an "error" message.
Hackers accessed the company's network in 2011, including the personal data of 77 million user accounts. Sony has said on multiple occasions their security has been upgraded since then.
