The weakest link in the emergency-power chain is the Controlled
Environment Vault (CEV). Many have only a few hours of battery
capability, and their battery maintenance is sometimes haphazard.
Some larger vaults have built-in or adjacent generators, but many
others have only a power plug that connects a portable genset which
must be transported, refueled, and safeguarded by mobile power crews
that can be thwarted by flooded intersections, downed trees, or
theft.
Let's face it: the "Alwways on, always works" phone service of my
youth has been replaced by "When we feel like it, you're not important
enough" compromises that follow economic lines. The only thing keeping
many low-profit areas in the power plans at all is the power of the
insurance lobby - along with politicians, both in fear of having to
actually deliver on their promises.
