Now that I've thrown in my share of late night sarcasm, It would interest me greatly to understand exactly why you came to the following conclusions:
1. The "operation" in Atlanta is Mickey Mouse
Both the Internet and the POTS system are telecommunications networks that are vital to the modern economy. POTS moreso than the Internet right now but the Internet is certainly heading in that direction. POTS exchanges are always in ground floor concrete buildings with no windows or underground. But in Atlanta they stick it up on the 5th floor of some office building?!?!?!?
I do not know where you get your data, but you are wrong. Many POTS exchanges in California, and many other parts of the country are not on the ground floor, or in basements. In fact, several of the POTS exchanges in San Francisco are on multiple floors of the same building.
2. The floor # of a bulding affects the quality of the Exchange Point 3. The type of building affect the quality of the Exchange Point
I cannot explain these ones but have reached this conclusion from observing how the phone company builds and locates its exchanges.
Must be specific to your phone company or an incomplete perspective of phone company methods. The primary reason for telephone exchanges of the past being built on ground floors and basements was the weight of the equipment and the difficulty of moving it. In modern times, the weight of the batteries still plays a role, but exchanges are being remoted away from the batteries with increasing regularity.
4. A city the size of Atlanta needs more than 1 Exchange Point
It has a lot more than one POTS exchange. Thus it will need more than 1 Internet exchange. Why should the packets from every video-call in the city all travel downtown when frequently the two parties live in the same neighborhood?
An interesting theory, but the Internet does not route information the same way the telephone system does. For one thing, you are comparing a connection oriented network to a connectionless network. There are subustantial differences.
Truly I would be very interested in your thoughts on these items, as well may a few other folks on this list.
I'm taking a long term view in which ISP's are just another form of telephone company. Many ISP's are now getting to the size where they can consider aquiring strategically located properties, building concrete block exchange/colo buildings, wiring up entire office towers with IP fiber and even running their own fibre in some case, especially in new subdivisions.
ISP's will never be another form of telephone company. ISP's who are viewing their role that way will not last long in the future. Even telephone companies will not maintain that role for very many years to come. You are trying to take a technology of the future and apply it to an obsolete model.
By today's standards Atlanta-NAP may be a really great thing, but too soon we will discover that we aren't living in "today" any more and the standards will be different.
Yes, they will, but I don't think they will go back to the Telco of the '50's.

Mae-East is pretty good example of this still.. those DC batteries didn't appear to me to be featherweights, up ontop of concrete blocks. I don't recall seeing DC batteries in mae-west up in the building.. where did they put them? The cost of building a datacenter in a multistory building is much much greater than a one story building, as we have learned. The only benefit we have seen from the multistories, is the usual coincidence that they are more likely to be "lit" with glass, than a vacant one story.. unless you are acquiring an old bell building or something.. owen ;) rob

Yes, it is, it was going to cost us about 30K to run 3Y 480 600 amps on the first floor. When we went with the 5th floor it went up to about 100K. Nathan Stratton CEO, NetRail, Inc.
