Check some trace routes and see where things go. Not sure how bad Shaw is with ignoring any and all IXs. But Rogers and Telus would send some 5km away end-point packet on a tour of the USA. No wonder why voip.ms seemed so shaky.

Like, hey Telus, you’re a Canadian ISP. Maybe peer in Canada instead of US only?

Teksavvy sells service in Shaw areas. Not sure which other independent ISPs do.

Can always use tor or VPNs, but need to understand their limitations and problems too.
