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.
