Looking at your tracert, I decided to try PingPlotter on that server. Note that routers sometimes delay or even drop the packets that detect the times for intermediate routes. Apparent loss or delays that do not continue into later hops would indicate that.
I selected some hops that were generally returning the packets, plus the endpoint. The pattern at the end point is interesting. I think it peaks during popular gaming sessions. The packet loss in red is on the right. Again, packet loss could be dropping packets by prioritizing other packets, but it can be useful. Also note that times for hop 9 peak times are larger than hop 16. Since hop 16 data passed through hop 9, that must be due to hop 9 prioritizing data packets. At calmer times, the hop 9 times are shorter.
