diversity?
In the old days of copper, there was path diversity. More than one route from point a to point b. This seems to be no longer the case. One thing that people forget is that the cell phones are always the first to go down. They need to insure path diversity, and media redundancy for critical systems (911, etc). Perhape back up fiber with microwave, for example. In this case, it was evildoers that cut the lines, but earthquakes can be just as effective. Having a redundant line in the same trench does you no good when the whole thing snaps. Whoever engineered away the diversity should be prosecuted as well.
