Nearly all Internet connectivity in Syria is down, according to Web-monitoring company Renesys. The blackout is consistent with operation of a government kill switch, Renesys says.

At 10:26 coordinated universal time today, 92 percent of the country’s networks went dark.

The only remaining functional networks belong to a different telecommunications provider than the rest, which belong to Syrian Telecommunications Establishment. Those that are still working “use Syrian-registered IP space, but the originator of the routes is actually Tata Communications,” according to Renesys.

The outage comes in the wake of some recent successes by forces fighting to outster Syrian president Bashar al-Assad.
