With a real risk of rota disconnection this winter, I have been looking into UPS and home battery backup solutions (which would also enable me to utilise off-peak tariffs). However, I have been unable to find out whether the broadband distribution cabinets in the road have a priority mains supply which would not be affected by rota cuts. There is no point in providing backup power for computers and routers if the broadband network shuts down. I asked an openreach technician and he didn't know. Can anyone give an authoritative answer?
Since FTP services remove the old analogue phone lines - and hence the ability to make emergency phone calls - I'm assuming a high level of resilience. But FTP subscribers would need mains power to their handsets in such a case, so maybe it's assumed that we will use mobile phones in any emergency during a blackout.
