Re: US/Canada International border concerns for routing

Hi Eric,


Allstream fiber goes counterclockwise from Toronto to Buffalo along the lake. Just like the rest of them. And at 
several places all these sysgtems are probably in the same conduit.


Finally, all fiber is exhausted Toronto/Buffalo. Existing players could not sell if they wanted to and no one selling 
dark on this route today.

It is worth noting, however, that the former AllStream ASN (formerly AT&T
Canada) AS15290 is a completely different thing, and has distinct
infrastructure and routing from the AboveNet ASN which is operated by Zayo.
Although they are probably using "Free" Zayo transport by now.

If I am grossly wrong and anybody from layer 3 network operations at Zayo
wants to chime in and tell us about the 40,000 ft view of their plans to
combine AS15290 and AS6461, I am sure the community would be very
interested.
