Power Loss but Still Online with Fiber Connection (beehaw.org)

Interesting experience, this has happened twice now. When house looses power I am still online now that I have moved to Fiber.

It feels a bit eerie. My network and computers, TV, media center, etc are all on UPS so they just keep going. Things just get really quite which is interrupted by just the periodic beeps of the UPS systems.

Does anyone know why my new Fiber connection does this but my old system which was bonded DSL did not? I know back in the early days of DSL I could do this, but some where along the way it stopped being power outage resistant.

DSL is just as capable of this as fiber optic. As long as both ends of the connection have power, your comms are fine, as you noticed in the early days.

My guess is that your more recent DSL service relied on a loop extender located near enough to your home that it was affected by local power outages.
