Do you have xfinity by any chance? And are you using their x1 combination modem/router in bridge mode with custom (non-comcast) DNS settings?
Because the exact same thing was happening to me at the exact same time. I’m no networking expert but when I checked the logs it seemed that every day Comcast would try to “fix” my (not broken) DNS settings. I had been using mullvad DNS and open DNS as backup but since switching to nextDNS the issue has stopped.
I don’t know enough about networking or DNS to offer any explanation as to why.
- dpedu 6y agoI have xfinity configured with custom DNS and used to have a somewhat similar problem. At the same time each day, DNS would stop working (but I could still reach plain IPs) for a couple minutes. It went away after I called them and had them "de-provision" and "re-provision" my modem. Basically deleting it from their system and readding it. For whatever reason, whenever I'm having chronic comcast weirdness, having them do this solves it. It sucks that this is the way things are.
