I'll give you this, as I said I was playing devils advocate. I fully agree 
with the concept of regionalized exchanging for small players.

Also, you can now buy transit cheaper than you can buy longhaul circuits
even at perfect utilization. Set local-preference subtract. :) I prefer 
this to hauling traffic from the east to west to east coast just to use a 
peer because you only have the one anyhow *coughcogentcough*.

But the traffic they send to you, they get to dump on your Tier 1 provider
a many points all over their network. You'd think that being primarily 
outbound and in a single location would be a good thing, wouldn't you. :)

There is still a single point of failure between yourself and your network 
provider, but that is not their problem.

The worst kind of failure is the kind where BGP doesn't die.

You're talking about Tier 1's here... How many engineers does it take to
plug in a line card? <answer left as an excercise for the reader>

But yes, when you put it all together at the end of the day, it's about 
trying to make money and prevent competition. Some networks simply see 
those goals down a different path.
