The Okanagan Internet Junction in Vernon B.C. has a BCnet Ubiquity 
connection. We have NEVER seen congestion delays inside BCNet. Whenever I 
traceroute the traffic always goes into the USA via Vancouver unless it 
is to an Ontario ISP who is connected to CA*Net or accessible via the 
Toronto exchange point. I have done traceroutes from a site in England on 
EUNet/GB that come into CA*net at Toronto or Montreal and thence to Vernon.

Or perhaps Mindlink's internal network is poorly engineered and the 
congestion starts there? Or perhaps a BCNet customer can be routed via 
Toronto if there are problems inside MCI USA whereas a BC-Tel customer is 
just screwed?

a MAJOR fibre cut in the Northeastern USA caused great havoc in traffic 
patterns for several days.

Yep! Now my routing to Wimsey goes to fONOROLA in Toronto and thence to 
Montreal, Ottawa and Vancouver...

That's right. Same traceroute as Wimsey

They connect to Westel who runs a line into Seattle.

A traceroute to them goes through the Ontario exchange point and thence 
back to Vancouver on a T1 line. They still have a T1 from Fort Worth up 
into Vancouver. I did a traceroute from inside BC-Tel to check this and 
was routed to Insinc via the PacBell NAP.

They have their own line (presumably a T1) direct to MCI in Seattle.

That's right!
