Not anymore. Once they run fiber to the neighborhood, they run out there and 
put out small gas generators in a mocking attempt to keep the POTS crap that 
runs to your house up when a hurricane comes through. In New Orleans (where 
I'm pretty much from, and where I'm back to since June) power was out for 5 
days a few years ago, and all you'd get from a landline was a nasty static. 
Phones and DSL were both out until the power came back on.
