Sony Computer Entertainment says its PlayStation Network was hacked, shutting down its global gaming systems. A company statement late Saturday said that Sony "was working around the clock" to fix the issues.
"An external intrusion on our system has affected our PlayStation Network and Qriocty services," said Patrick Seybold, Sony's senior director of corporate communications and social media.
The PlayStation Network is a way for users to download movies, TV shows and games over the web to a PlayStation. Access to the network is free, though users have to pay for some of the content.
Meanwhile, Amazon.com is still working to restore some of its servers used by other websites as an outage stretched into a fourth day. Besides selling books and DVDs, Amazon.com rents out space on its servers that run other websites and online services. Amazon said Saturday that it was making progress fixing the problem, but more slowly than it had hoped.
