This follows a ruling at the European Court last year that Verisign's actions in blocking the domain of German business Musikjetzt GmbH constituted an unlawful restraint of trade, and a subsequent European decision that all primary DNS management should be run under the newly formed United Nations Internet Oversight Service.

Shares in major US record labels have fallen over 40% in the past year, which industry insiders have repeatedly blamed on the way that Europeans "don't respect copyrights." As one CEO put it, "If they won't respect our rules voluntarily, we have to make them respect them."
A spokeman for the US Immigration and Customs Enforcement agency said "Economic attacks on fundamental US industries are a bigger threat than terrorism, and we will always respond accordingly."
No-one from the Recording Industry Association of America was available for comment.
