Comcast came back up around 7pm.
I was keeping the Zello push-to-talk channel updated, since that is a great way to keep in touch when the internet goes down. I walked around the Shoshone loop, took pictures and chatted with the Comcast guys. You can see the logs.
Install the Zello app on your phone, then search for the channel “BigTreesVillageCalaveras”. (need to type it all).
Zello was highly instrumental during the Hurricanes earlier this year, both the rescue personnel and the neighborhoods found it essential.
