A hacker group calling itself the “Lizard Squad” has claimed responsibility for attacking Sony’s online PlayStation network.

Gamers who visited they PlayStation store Sunday were greeted by a message that said “Page Not Found! It’s not you. It’s the Internet’s fault.”

The hacker group took responsibility for the attack via a posting to Twitter.

The outage is the most recent hacking attempt against Tokyo-based Sony (SNE). The company’s Hollywood film studio was targeted last month, resulting in an online leak of unreleased movies, as well as a list of confidential salary information.

It isn’t the first time Sony’s PlayStation network has been a target for online attacks. A hacking attempt in late August led the company to temporarily take its system offline after an influx of artificially high traffic overwhelmed the service — an event that’s referred to as a DDoS, or a distributed denial of service attack.

Rival gaming system Xbox, a division of Microsoft (MSFT), was the victim of a similar attack last week. Lizard Squad claimed responsibility for that incident as well.

The hacker group, an anonymous collective with a Russia-based website, said the attacks are a taste of further targeting to come over the holiday season.

Lizard Squad has also claimed responsibility for past attacks on other gaming targets, such as Electronic Arts (EA) games and Destiny offline.
