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?
