* U.S. PlayStation website not working in Japan
* Says new security measure responsible for disruption
* No new attack occurred on PlayStation website (Adds detail on U.S. website being down; adds news of Bloomberg's correction, byline)
NEW YORK, May 11 (Reuters) - A security measure that Sony Corp (6758.T) (SNE.N) installed made one of the official PlayStation websites unavailable in Japan.
The company published a statement about the site on Wednesday after a Bloomberg report said the site was down because of a hacker attack.
Sony uses its PlayStation website to update the public about a break-in to its servers which compromised the personal data of more 100 million users.[ID:nN10109945]
The website is separate from the PlayStation Network, the online gaming hub where users can buy and download video games. It has been offline since April 19.
An earlier report by Bloomberg saying that hackers had attacked the PlayStation blog was incorrect, said Sony spokesman Dan Race in a statement.
"Media reports claiming that the US PlayStation.com site and blog were partially disrupted because of hackers are false," he said. "We installed a new security measure that has temporarily made the sites inaccessible to select regions outside of the US."
The report circulated through the Twitter online social network and was picked up by at least one news website.
Bloomberg corrected its story. A Bloomberg representative was not available.
Users in Japan can still get access to PlayStation websites, just not the U.S. version, Race said, adding that Sony is working on getting it back online as soon as possible. (Reporting by Liana B. Baker. Editing by Robert MacMillan)
