Hi, We're looking to extend some services into Canada. While our lawyers dig into it, I thought that I'd ask the hive mind about border restrictions.
For traffic routing, is anyone constraining cross-border routing between Canada and the US? IOW, if you are routing from Toronto to Montreal, do you have to guarantee that the path cannot go through, say, Syracuse, New York?
Guarantee to whom? Back a few years ago when I looked into it, most of the traffic within Canada went through the US, e.g., since Bell didn't want to peer with anyone in Canada, you'd go something like YYZ - ORD - YYZ, clearly visible through the traceroute. Possibly somewhat better nowadays — there's been quite a few new IX POPs that popped up — but I doubt the scenario is a thing of the past. P.S. Just for the giggles — checked http://lg.he.net/ routing from core1.tor1.he.net to www.bell.ca — still goes through Chicago, to Montreal, from Toronto. :-) Going straight to Montreal, core1.ymq1.he.net, will route you to www.bell.ca (still in Montreal) through the peering at NYC. P.P.S. In other words — if someone wants guarantees, they better explicitly ask you for it. Cheers, Constantine. http://cm.su/
