i'm not sure one necessarily fails to the other... if people don't subscribe to the other for restoral or if they're supersmart-- to one of the transrussia overland routes, they're out of luck.<br><br>i frankly don't believe enough capacity exists on the transrussia cables to backup swm3 and swm4.<br>

Does anyone across the pond have any further insight into this cut?<br>
<br>
Although SEA-ME-WE 3 and 4 are suppose to provide redundancy for<br>
eachother, not sure what impact has SMW4 segment caused, maybe latency?<br>
<br>
<br>
Any feedback will be appreciated.<br>
<br>

There's a cut in SWM4<br>
<br>
*SMW4 Segment 4.1 cable fault*<br>
<br>
Cable shunt fault developed on SMW4 segment 4.1 (Egypt / Alexandria –<br>
Branching Unit #4A onward France / Marseilles) at 07:15GMT on 14-Apr. 2010.<br>
However the shunt fault has further deteriorated and the cable segment was<br>
down at 10:03GMT. Only four unprotected Singapore – London / Frankfurt<br>
STM-4c IP trunks were being affected.<br>
<br>
SMW4 NOC updated that there is a shunt fault in segment 4.1 between Egypt /<br>
Alexandria and France / Marseilles with cable fault on Fiber Pair #2 at<br>
1886.152 km from Alexandria towards Palermo. The traffic landed at Palermo<br>
onwards to Europe was being affected, while the traffic running between<br>
Alexandria and Marseilles via Fiber Pair #1 is still maintained.<br>
