It's very difficult to properly build a resilient infrastructure when those shareholders must get their value! 
The FCC asked a half-dozen carriers about their network resilience plans 
last month.  Comcast was not one of the service providers askedd about 
their plans.
The FCC should have looked closer at Comcast in California. While it was 
expected many people would loose home Internet, voice, video service when 
their Customer Premise Equipment lost power.  The FCC no longer requires 
battery backup for CPE.  That is now a customer responsibility.
It turns out, Comcast's outside plant was woefully unprepared to handle 
long, i.e. 24 hour, power outages.  And even when power is restored to 
people's homes, Comcast service is often still down.

Maybe the FCC needs to ask about cable system Outside Service Plant 
network reslience of Comcast.  Are other cable OSP resilience similar?
