Outside plant protection, fiber cuts, interwebz down oh noes!

Not to turn this into an ethical typ discussion but this arguement would have to assume you could sue the telco not the 'vandal' due to a loss of life if it occured, and that, that dollar amt would be greater then 'securing' all cables.  

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.

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.

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?
