At exactly 14:01 UTC Tuesday (09:01 local time), Renesys saw a third mode in their latency tests. In this plot, you can see the original pure-satellite mode (A), the apparent one way satellite mode we mentioned in an earlier post (B), and a third, lower mode (C) that indicates two-way cable connectivity.
It seems there is a mix of satellite, one-way cable and bi-directional cable connectivity.
