If that is a prime time ping plot, then that is pretty darn good, especially for Level3. That hub must have been upgraded or never really busy to begin with. Too bad the rest of the country does not look like that. If it did, we would get zero complaints about lag, packet loss (switching to TCP from UDP), or a melee of other network related complaints.
It still does not stop Comcast from altering network priority and order of packets on their network, which is still an issue.
