It is worth mentioning that the value of SONET redundancy has a lot to
do with your location to the ring.  SONET's value is proportional to the
available space for backhoes between your location and the point where 1
trench splits into two trenches, if this ever occurs, prior to hitting
the SONET ring.

For instance:  If you are more likely to experience digging near your
location, then SONET may not really be worth the cost as nearby
trenching activity could just as easily knock you off the ring.

SONET is very good if you are worried about the provider's metro network
confronting a backhoe.

Does anyone have any good statistics on SONET outages?
