I live in an apartment building in Czech Republic, Europe. I have a cable internet connection with a static IP connected to an Ubuntu server I set up. Recently out building lost power, though the elevators and emergency lights continues functioning on some secondary emergency power supply.
I was thinking of buying an UPS unit to keep my cable modem, router, and MiniITX Ubuntu server running during a power outage. I know that when I lived in the US, telephone(edit-removed: /DSL) connections will continue to function because they have their own power source.
So, if I hooked up a UPS, would my connection remain alive? Or do cable internet connections rely on repeaters/signal boosters/etc. which use the local power source?
2correction, in the US, POTS telephones still work because they're powered by the telco's equipment. wireless phones & consumer DSL modems are powered by the location's power, so they won't function during a power outage without battery/generator backup. – quack quixote – 2009-10-22T19:25:45.817
