Interesting that the local network will actually continue to work pretty well if your #DHCP server just...forgets to give out the DNS addresses for a couple days. Windows, IOS, OSX, Android, and Debian will all just kinda roll with it. That's not to mention annoying stuff like Firefox that refuses to use your system provided #DNS by default because it's special. But you get weird failures with anything custom (tvs, cameras, etc). So anyway, that was what I spent my evening diagnosing.
