"Preliminary analysis of more than 25,000 traceroutes reveals a

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.
