Syrians poured into the streets on Friday...despite the shutdown of much of Syria’s Internet network, which has been crucial to demonstrators’ ability to mobilize and a major source of information for those outside the country...The Internet shutdown severely disrupted the flow of the YouTube videos and Facebook and Twitter posts that have allowed protesters and others to keep track of demonstrations, since foreign news media are banned and state media are heavily controlled...Skype had become a major means of communication among activists, and its loss as a tool may be a blow to the protest movement...Forty of the country’s 59 Internet pathways were disabled, including Syria’s entire 3G mobile network, run by the country’s only telecom provider, Syriatel, which is owned by Rami Makhlouf, Mr. Assad’s cousin.
