I can confirm here that my traffic to this site is routed through Toronto then
Chicago - does synclive use a local P2P connection pool to other participants
when it's not going to the main site? I can't see why if it's going to Chicago,
then it would stay in Ottawa otherwise.
However, paradoxically: I also see the same result when I ping between two ISPs
listed as on OGIX to their main web site. I am not aware if I am missing
anything here as a user. Perhaps I did not pay for OGIX access in my more
basic plan and no general bulk users get that route. (See results below.)
Can anyone with another ottawa colo provide an IP to ping/traceroute from
another OGIX peer? I want to see it work, so far no luck keeping the traffic
local between ISPs.
A bell fibre circuit is said to be terminated in Toronto, and as such wouldn't
be local to Ottawa, anyway with a given local ISP - so the Toronto exchange is
the one you want to be local to for most Ottawa traffic - except if you are
near Montreal perhaps?
Thus any Tor / Ott colo would do for this task if your users are connected
through that same exchange. Can't see how the ping time would get an lower
otherwise - thus in agreement with the original poster.

It's certainly not the default for TekSavvy or Rogers; which definitely use
Toronto for their cable modems, even just to get your cable modem online -
you're out to Toronto already - as many might have known. But is Rogers nice
enough to route between cable modems in the same neighbourhood or city for such
P2P / realtime applications? This I cannot confirm.

According to syncspace.live right here:
https://syncspace.live/get-started/
"With these kinds of situations, it may mean that it is best to use a
server in a different city. For example, if everyone in an ensemble is
getting 5ms to the server but some people are getting 30ms because their
traffic is being routed out of town and then back, it may be best to
locate the server in one of those cities that the traffic is going
through so that everyone gets roughly equal latency even though it might
not be as low as it could be for some people. These routing problems
with ISPs are beyond our control and we already put in a huge amount of
effort to locate our strategically in the most central places with the
best peering so that we can offer the lowest possible latency for the
largest number of people in that city.
If you need help sorting things out or you have more information to add
regarding problematic routing in one of our regions, please feel free to
contact us."
