Ah yes, I now remember some of you adding the TD-69. I think the key would be whether or not the “outage” was enough to trigger the TD-69 itself. In my case it was quicker than a blink of an eye. Just enough for you to think to yourself “did I blink or did the lights flicker?” Every device in the home, except Sense, properly recovered.
All of our home’s network gear, including access points, are on UPS backup and Verizon FiOS’ local gear is also on battery backup as they power telephone calls in addition to Internet connectivity. When we have real power outages our network connectivity is typically unaffected for hours until Verizon’s or our own UPS run out first.
