[AusNOG] SEA-ME-WE 3 cut again

[Bevan Slattery]

The challenge with SMW3 is that the segment from about 200km south of
Indonsia all the way to Singapore is in less than 60m of water depth (about
1,400km).  Ideally cables are deeper than 2,000m of water depth away from
anchors and long-line fisherman :)

The other challenge is that some sections of this route it is almost
impossible to bury due to the ocean floor being rocky and not ideal for
burial.  Sometimes there is an alternate route, but it would add significant
latency, something that people in 99% of circumstances prefer.  The 1% of
the time they don¹t mind latency is when the cable is not functioning due to
a shunt fault or a cut, which could have been avoided if they went the more
safer, less commercial route :)

There is a history of intentional cable cut/theft in these waters by people
initially interested in the perceived copper/raw materials.  There is a
notorious stretch between two (2) islands in which nearly all cables pass
and due to the rock formations and depth these cables can¹t be buried and
are easily damaged either intentionally or otherwise.  Despite the
investment in education and armouring things still happen.  An example can
be found here:

eplacing-stolen-underwater-cable.html

Also I think last time there was a combination of factors being a shunt/cut
and a repeater ³pop² needing two (2) permits to complete.  Others on the
list would have a better background as to what happened last time and what
is happening this time.  I will make some calls and get an ETA.

Cheers

That's my understanding of the last delay, I assumed it might face similar
issues this time. 

Hopefully I'm just being a little too pessimistic!
