WASHINGTON--The Recording Industry Association of America's Web site was unreachable over the weekend due to a denial-of-service attack.
The apparently deliberate overload rendered the RIAA.org site unavailable for portions of four days and came after the group endorsed legislation to allow copyright holders to disrupt peer-to-peer networks.

The malicious flood started on Friday and did not involve any intrusion into the RIAA's internal network, a representative for the trade association said on Monday afternoon. Nobody has claimed credit for the denial-of-service attack, which ended at 2 a.m. PDT on Monday
