Wow. Didn't even know that. But I'm not sure the cable-cutters have yet mapped out the fiber rings and how they are interconnected, in order to make appropriate cuts that will bring the traffic down (if that's actually their goal). Sure, repairing cable cuts is expensive, but the cuts don't really have any long-term impact. -TD

There's a cut in SWM4

*SMW4 Segment 4.1 cable fault*

Cable shunt fault developed on SMW4 segment 4.1 (Egypt / Alexandria b Branching Unit #4A onward France / Marseilles) at 07:15GMT on 14-Apr. 2010. However the shunt fault has further deteriorated and the cable segment was down at 10:03GMT. Only four unprotected Singapore b London / Frankfurt STM-4c IP trunks were being affected.

SMW4 NOC updated that there is a shunt fault in segment 4.1 between Egypt / Alexandria and France / Marseilles with cable fault on Fiber Pair #2 at 1886.152 km from Alexandria towards Palermo. The traffic landed at Palermo onwards to Europe was being affected, while the traffic running between Alexandria and Marseilles via Fiber Pair #1 is still maintained.

Seeing a serious uptick in latency to India from North America and am hearing reports of an undersea cable cut in the Mediterranean? Has anyone else heard something similar?

Thanks, Adam
