Technology yesterday achieved what the largest music companies have failed to do - knock controversial music-sharing site off the Web, at least for a few hours.

The controversial site was down for at least two hours, due to "equipment failure," according to a Napster spokesperson.

Napster is in the middle of a copyright infringement suit filed by the Recording Industry Association of America (RIAA), representing the largest music companies.

A date for the trial itself has yet to be set, but meanwhile a U.S. federal appeals court on Monday heard arguments from both sides in the case on the matter of an injunction barring the file-sharing music Web site from operating.

The three-judge panel could take months to rule on whether Napster will have to shut down, however.
