The cost to fix all pintos' gas tanks was only $11 per car unit and
it was gambled, though they lost it was cheeper then the lawsuits,
I'm betting the while fewer units, its order of magnatitudes more
then 11$ per unit to 'secure' access points with a lot less certain
negative lawsuit outcomes. Sent from my BlackBerry device on the

I regularly drove on these roads when these lines were being put in
 up-and-down the SF Peninsula.  There are 4 manhole covers every
1/4 mile or so that provide access to this fiber.  Do the math.
Multiply by the number of miles of fiber runs across the world, and
the number of access points per mile on each run.  Exactly how do
you plan to make "vault access non-trivial" and yet make the access
as easy as it needs to be for routine maintenance and repair?

Having never been in a vault or know how to get in one other than 
apparently lifting a manhole cover I can't possible answer that with
anything more than guessing.

My guess is that it is probably less expensive in the long run to
leave them unprotected and just fix the problems when they occur
than to try to "secure" the vaults and deal with the costs and
extended outage delays when access it "secured" and it takes longer
to get into a vault to fix things.

I wasn't thinking Exodus/C&W/SAVVIS/Whoever level security, but 
considering communications cables traverse such sites it is hardly 
unreasonable to think they could implement some alarm that is 
centrally monitored by a NOC.  I'm guessing *anything* is better than
what appears to be the *nothing* that is in place now.

Also not to get sensationalist, but less expensive than a life that 
could be lost if an emergency call can't be put through?
