The Syrian government has blacked out nearly the entire country’s access to the internet.
A global internet monitoring firm, Renesys has stated:
“Starting at 10:26 UTC (12:26pm in Damascus), Syria’s international Internet connectivity shut down. In the global routing table, all 84 of Syria’s IP address blocks have become unreachable, effectively removing the country from the Internet. We are investigating the dynamics of the outage and will post updates as they become available.
…We can see that traceroutes into Syria are failing, exactly as one would expect for a major outage. The primary autonomous system for Syria is the Syrian Telecommunications Establishment; all of their customer networks are currently unreachable.”
