Is it a cordless phone you have too?
I have seen the destruction caused by storms , invariably the current phone system is disrupted as well as the power , if your objection is that the storms could disrupt power , those same storms would undoubtedly disrupt your existing phone service , if you are in an area susceptible to these natural forces , your phone lines which are also overhead are just as likely to be brought down as power lines …therefore DV is likely no more or less ‘risky’ than what you currently have ,
This is totally pointless, as has been said a thousand times over on this thread and others, DV is going to happen. Get over it.
If the power is out it is a power company problem and they should supply a solution and I think I'd be more worried about other things that do not work as a result of no power for a prolonged period such as you have described.
As regards being kept informed from the power company, you'll know when they have restored the power, the lights will come back on!
