Historically, the largest telecommunication outages have been due to 
operator error & software bugs (or the malicious equivalent). Problems in 
large networks have more impact.

Vulnerability to physical damage varies a lot between countries.  Some 
countries have a lot of redundancy, other countries have limited 

The big question for decision makers are trends.

Are these 'normal' outage trends or 'unusual' outage trends.  One farmer 
on a tractor digging up fiber may be normal. Two farmers is a concidence. 
More than two farmers is abnormal.
