The only connection that these sites have to the US appears to be that they are operated by American companies. This is only a temporary setback, as all the owners of the above sites are determined to continue their services. They have simply started moving their operations to alternative domains, since the actual servers are still intact. It has already begun: rojadirecta.com is now available at rojadirecta.es, channelsurfing.net is now at channelsurf.eu, atdhe.net has moved to atdhenet.tv, and ilemi.com has transferred over to Ilemi.tv.
