US-based network security firm Renesys has said that internet lines in Syria have been cut, following the civil unrest in the country. "Over the course of roughly half an hour, the routes to 40 of 59 networks were withdrawn from the global routing table," the group said. Syrian internet access is primarily controlled by the state-owned SyriaTel. "They buy most of their internet transit from Turk Telekom and Deutsche Telekom, with some contribution from PCCW, Tata, and Telecom Italia," Renesys said. "Connectivity has historically come in over submarine cable from Cyprus; activation of new terrestrial fibre connections to Turkey have been delayed by this year's political unrest."
