AT&T: 888,000 route miles(1).
Verizon: 485,000 route miles(2).

If we assume that 1/4 of AT&T and Verizon's route-miles are in the US(3), this would mean a capital expense of $666M and $364M respectively, not including any costs incurred for maintenance, monitoring, repair, false positive etc.  In addition, as has been noted, this system wouldn't PREVENT a failure, it would just give you some warning that a failure may be coming, probably by a matter of minutes.  

In the words of Randy Bush, "I encourage my competitors to do this."
