What does Bell buying MTS do? Does it change your statement or will the MTS portion of Bell still peer locally?

So, they’re capable of keeping traffic in Canada so long as the other end isn’t on Bell or Telus, which only sell U.S. bandwidth to Canadians.

> As has been pointed out, Canada has been building IXPs… Just not as fast as the rest of the world has. They’re behind the global average growth rate, and behind the U.S. growth rate, which is why the problem is getting worse. Bandwidth costs are falling faster elsewhere, so they’re importing more foreign bandwidth.
