My experience is that a lot of the BB providers route through NAPs/MAEs
when they have local peering. The Internet IS more brittle than it needs
to be, because routing seems to be a lot more static than it should be.

Which leads me to my operational question.

If you know that someone wants to cut your cables.  What defense do 
you have? Is there any practical way to monitor and protect 
an oceanic 
cable? Are there ways to build them that would make them less 
discoverable? Some way to provide redundancy?  A 
non-physical solution 
involving underwater repeaters? Or is this like pipelines in Iraq?

The other answer is to be less dependent on the cables.

Some communications need to be long distance -- talking to a 
specific person in a far away place, setting up import/export 
deals, calling tech support -- but a lot don't.  E-mailing or 
VOIP calling your neighbors, looking at web sites for local 
businesses, reading your local newspaper or accessing other 
local content, or telecommuting across town, all ought to be 
able to be done locally, without dependence on international 
infrastructure.  Yet we keep seeing articles about outages of 
"Internet and long distance telephone" networks, implying 
that this Internet thing we've all been working on is pretty 
fragile compared to the old fashioned phone networks we've 
been trying to replace.

The report from Renesys
(http://www.renesys.com/blog/2008/02/mediterranean_cable_break
_part.shtml)
looks at outages in connectivity to India, Pakistan, Saudi 
Arabia, Kuwait, and Egypt.  I'll assume that those areas 
probably did keep some local connectivity.  India has its 
NIXI exchanges, although my understanding is that they're not 
as well used as one might hope.  Saudi Arabia has a monopoly 
international transit provider, which should have the effect 
of keeping local traffic local.  Egypt has an exchange point. 
 I don't know about Pakistan or Kuwait.  Unfortunately, 
little else works without DNS. 
Pakistan and India have DNS root servers, but Pakistan's .PK 
ccTLD is served entirely from the US.  Saudi Arabia, Kuwait, 
and Egypt all have servers for their local ccTLDs, but do not 
have local root DNS servers. 
Of that list, only India has both the root and their ccTLD 
hosted locally.

And then there's the rest of the services people use.  Being 
able to get to DNS doesn't help people talk to their 
neighbors if both they and their neighbors are using mail 
services in far away places, for instance.
