Sony’s PlayStation Network suffered an outage of several hours Sunday night, extending into early Monday morning U.S. time, with a group that previously claimed to have disabled PSN reportedly taking credit for the attack.
According to Sony Computer Entertainment, the PlayStation Network was mostly down from 8:52 a.m. to 11:18 a.m. Tokyo time, with some users seeing the message: “Page not found. It’s not you. It’s the internet’s fault,” FT reported.
[UPDATE, 11:20 AM PT: Sony Computer Entertainment said in a statement: “The PlayStation Network and Sony Entertainment Network are back online and people can now enjoy the services on their PlayStation devices. The ability to access our network services was temporarily impacted due to a distributed denial-of-service attack. We have seen no evidence of any intrusion to the network and no evidence of any unauthorized access to users’ personal information.”]
The latest PSN outage appears to be completely separate from the attack two weeks ago on Sony Pictures Entertainment. The studio has been reeling from that hack, which disabled its internal systems for about a week and has resulted in employee info, other data and at least five movies being posted online. Cyber-attckers with ties to North Korea have been suspected in the SPE incident; the communist regime has officially denied responsibility for that attack, while also calling it “a righteous deed” that may have been executed by supporters.
In the recent PlayStation Network outage, a group called Lizard Squad — which had previously claimed responsibility for PSN and Microsoft Xbox Live outages in August 2014 — appeared to take credit, FT reported. On Sunday, the group tweeted: “PSN Login #offline #LizardSquad” after the PlayStation Network went down. Lizard Squad last week tweeted “Xbox Live #offline” after Microsoft’s Xbox Live users had trouble signing in.
The August 2014 outage of PlayStation Network (which another group also claimed to be behind) was the result of a distributed denial-of-service attack, in which bogus information overwhelms a system’s servers. In such a DDoS attack, private data is not accessed. By contrast, a security breach in 2011 exposed the names and passwords of millions of PlayStation Network customers.
Sony’s official PlayStation twitter account posted a message at about 9 p.m. Eastern Sunday about the issue:
PSN update: we are aware of the issues some users are experiencing, and are working to address them. We'll keep you updated.

At 4:05 ET Monday, the PlayStation twitter account had an update that said, “If you had difficulties signing into PlayStation Network, give it a try now.”
