BEIRUT – Internet and telephone service were restored across much of Syria on Saturday after a two-day, nationwide communications blackout that came during some of the worst fighting to hit the capital since July.

Experts say the shutdown was likely caused by President Bashar Assad’s regime, raising fears that the government is taking increasingly bold measures to cut off the country from the outside world as it tries to crush a relentless rebellion.

Renesys, a U.S.-based network monitoring firm that studies Internet disruptions, said in a statement Saturday that service went back up around 4:32 p.m. local time in Syria, describing it as a “largely complete restoration of the Syrian Internet.”
