CWmike writes "In what appears to be the latest bid by a government to throttle access to news and information amid growing civil unrest, the Syrian government Friday shut down all Internet services. Internet monitoring firm Renesys reported that starting around 7 a.m. EDT today, close to two-thirds of all Syrian networks were suddenly unreachable from the global Internet. In just 30 minutes, routes to 40 of 59 Syrian networks were withdrawn from the global routing table, Reneys' chief technology officer James Cowie said in a blog post. The shutdown has affected all of SyriaTel's 3G mobile data networks as well as several of the country's ISPs, such as Sawa, INET and Runnet. Also down are the Damascus city government page and the customs web site. The only networks that appear to be somewhat reachable are a handful of government-owned networks such as one belonging to Syria's Oil Ministry, Cowie noted. 'We don't know yet how the outage was coordinated, or what specific regions or cities may be affected more than others,' Cowie wrote. 'If Egypt and Libya are any guide, one might conclude that events on the street in Syria are reaching a tipping point.'"
