We see good cable modem connectivity during power outages. Batteries 
must still be good in the HFC nodes in our area. Verizon POTS 
service, on the other hand, dies when the power does. The batteries 
in their SLC units are toast. I've got the local police chief off 
conversing with the Verizon E911 folks to find out why it's OK to 
have no 911 service to a large part of town when there's no power 
(Verizon repair kept trying to tell me it must be my equipment, 
despite testing at the network interface).

I am looking at moving telephone services off to Comcast or VOIP 
because they're more reliable than Verizon is, in my particular neighborhood.
