This, unfortunately, is a highly-charged and highly emotional topic.

Part of the problem with "public exchanges" is that they get congested.  But
the REASONS for that congestion are not, I believe, that well understood.

Can we just build faster exchanges?  Sure.  Will it solve the problem?  Not
if carriers don't provision fast enough circuits into them!

If you're seeing poor performance between <X> and <Y> at an exchange, is 
it due to the exchange fabric's poor performnace, or is one of <X> or <Y>
under-provisoned into that fabric?  Have either of those carriers
DELIBERATELY (or through negligence) failed to provide adequate 
connectivity to the exchange?  

How do you determine which is the case in these situations?

I'd love to see an exchange which PUBLISHED the "saturation rates" at each 
*PORT* to the world, identifying the carrier and speed of connection at 
each PORT.  Also, in the same breath, they would need to publish the total 
FABRIC capacity as well as its saturation.

That would mean that those who say "oh, don't route though <X>, come to 
this nice private interconnect (perhaps at some cost)" would get called on 
the carpet if the reason for their statement was that they had impaired 
performance through the exchange due to a lack of appropriate commitment.

Likewise, if the *EXCHANGE* operator was negligent (or just unable to keep
up with demand) we could hold THEIR feet to the fire as operators.

Sadly, I know of NO exchange currently in operation that subscribes to these
operating rules and policies.
