Syrian Internet Shutdown
Starting at 3:35 UTC today (6:35am local time), approximately two-thirds of all Syrian networks became unreachable from the global Internet. Over the course of roughly half an hour, the routes to 40 of 59 networks were withdrawn from the global routing table.
Context & Ripple Effects
Syria has a long filtering record — it blocked Facebook in its 2007 Internet crackdown, a move covered again weeks later when access stayed shut — but filtering content is different from what Renesys measured today: BGP routes to 40 of 59 Syrian networks withdrawn from the global table within half an hour, starting 3:35 UTC.
The move lands in a regional arc Renesys has been documenting all year, beginning with February's Libyan Disconnect and followed by Libya's full Internet block in early March. The Washington Post's same-day framing ties the timing to protesters filling Syrian streets, making this the second Arab Spring state this year to reach for the routing table rather than just the filter list.
First-order effects
- Most of Syria goes dark from the outside: roughly two-thirds of Syrian networks are unreachable globally, severing ordinary connectivity for users and cutting off real-time reporting exactly as demonstrations peak.
Second-order effects
- Syrian businesses, ISPs, and the diaspora lose their communications channel overnight, while the government demonstrates — as Libya did earlier this year — that national disconnection is operationally feasible on short notice.
Third-order effects
- If the Libyan and Syrian precedents harden into a playbook, border networks themselves become instruments of crowd control, pushing activists toward workarounds and raising the stakes of how much single-point control any state retains over its national routing.
The trend: States under protest pressure are graduating from website filtering to wholesale withdrawal of national routes from the global routing table, with Syria following Libya's 2011 template.
