"Preliminary analysis of more than 25,000 traceroutes reveals a phenomenon we call ‘boomerang routing’ whereby Canadian-to-Canadian internet transmissions are routinely routed through the United States.
I sincerely hope that nobody in Canada is surprised by this, since it was already an issue in 1994 (when I was at CA*net).
Much farther back than that. In 1985 I was working in Toronto and did a proposal for a national X.25 network. The pragmatics for reliability were simple at a national scale: Essentially all Canadian telecom links went through a few common sites across the country; if you wanted redundancy you had to have a second, independent path through the US. Given that most Canadian population occupies a relatively thin band (close to the US border), this topological fragility was/is largely inherent. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
