At 10:30 AM GMT yesterday, 29 November 2012, routing to Yemen suddenly changed from London to Dubai through FLAG to New York to Dubai through ETISALAT, as shown in the animation here and detailed in the PerilWatch from InternetPerils. That timing closely matched the 10:26 AM GMT Syrian disconnect time reported by Renesys. This is very reminiscent of Mubarak disconnecting Egypt 22:30 GMT 20 January 2011. This tactic didn't help Mubarak's regime in Egypt, and it probably won't help Assad's regime in Syria; rather the opposite: people don't like their Internet being turned off. And it tends to cause the international community to rally around the rebels.
