I can tell you from experience that rebooting the router may not be enough. It has to be reset sometimes in order to refresh the routes.

The fact that it's not even getting *PAST* your router is a little suspicious. One would think it would at least get one hop out. Granted, there COULD be a routing/BGP issue between Comcast and Level3. It wouldn't be the first time. But again, one would expect that at least one hop out. -derek On Tue, May 19, 2020 12:02 pm, Jerry Feldman wrote: Yes I get 216.235.254.230 also. That is the first thing I check.
