A Canadian ISP colleague of mine suggested that the NANOG constituency might be interested in this, given some recent 'revelations', so I forward it here for you perusal. "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. Canadian originated transmissions that travel to a Canadian destination via a U.S. switching centre or carrier are subject to U.S. law - including the USA Patriot Act and FISAA. As a result, these transmissions expose Canadians to potential U.S. surveillance activities – a violation of Canadian network sovereignty." http://lawprofessors.typepad.com/media_law_prof_blog/2013/09/routing-interne...
