In a demonstration of their growing sophistication and organization, Syrian rebels responded to a nationwide shutdown of the Internet by turning to satellite technology to coordinate within the country and to communicate with outside activists.

When Syria’s Internet service disappeared Thursday, government officials first blamed rebel attacks. Activist groups blamed the government and viewed the blackout as a sign that troops would violently clamp down on rebels.

But having dealt with periodic outages for more than a year, the opposition had anticipated a full shutdown of Syria’s Internet service providers. To prepare, they have spent months smuggling communications equipment like mobile handsets and portable satellite phones into the country.

“We’re very well equipped here,” said Albaraa Abdul Rahman, 27, an activist in Saqba, a poor suburb 20 minutes outside Damascus. He said he was in touch with an expert in Homs who helped connect his office and 10 others like it in and around Damascus.
