I understand that you should be ok with broadband staying up with ADSL
but do you know if those of us on cable would be ok? Eg, are the green
cabinets (assuming they aren't passive) remotely powered or have a UPS
of their own etc?

I'm on VDSL, and the BT cabinets with the DSLAM/MSAN have battery backup.

The Virgin cabinets here only pass photons, no electrons, so presumably
the headend is UPS/generator backed?
