Curious question, latency as we know is a big factor in online gaming, the two state rewind systems in place have done significant amounts to reduce the impact of latency.

So why is it that traffic is routed into the US, and then for one hop up to canada to then come back down to Atlanta where the game servers are which produces a significant jitter effect (because of the added distance) more prominent to those overseas.

What is the functional purpose of this hop to canada? and is it not something that could be relocated to the game servers reducing the hops and improving latency.

For example.

Tracert: 70.42.29.74


01 86.20.0.1 10 ms 20 ms, 20 ms
02 213.105.114.97 20 ms 10 ms, 10 ms
03 62.253.174.77 10 ms 10 ms, 10 ms
04 62.253.174.102 20 ms 10 ms, 30 ms
05 62.253.174.146 10 ms 20 ms, 20 ms
06 213.105.159.30 10 ms 10 ms, 60 ms
07 62.253.185.81 50 ms 70 ms, 30 ms
08 130.117.14.133 40 ms 40 ms, 40 ms
09 130.117.3.85 40 ms 40 ms, 30 ms

10 154.54.76.114 40 ms 40 ms, 40 ms
11 154.54.87.58 130 ms 110 ms, 110 ms
12 154.54.44.98 120 ms 110 ms, 130 ms
13 38.104.159.26 190 ms 230 ms, 180 ms
14 70.42.24.196 120 ms 130 ms, 120 ms


Now most of that is fairly normal the points to note.

Hop 10 154.54.76.114 - Is a Cogent Communications hop inside the US near Wichita.
Hop 11, 12 are in the same location and the latency picks up mostly expected given the distance again managed by Cogent.

Hop 13 is the criminal in this case, located in canada which sees substantial increase in latency to then be routed back down to Atlanta.
