### This page is very out of date - the last update was in 2002 ###

Most of this information is based on my recollection of facilities I've been in. As it is based on memory it likely contains some errors. I'll gladly correct any mistakes I am notified of. Mail me - andy@andy.net

This guides contains facilities with >1000 sq. ft datacenters in the metro Atlanta area which offer collocation services. Note, not all listed datacenters offer transit. Some locations are more carrier oriented or in close enough proximity to a Meet-Me-Room that the operators expect you to establish your own transit.

I need to add a number of things to this page in some cases I already have the info in others I don't. If you can contribute additional facts about a location please let me know. (Please keep in mind any NDAs you may have signed before you send me info).

Providers I know very little about:
(A few folks have asked me if these providers are in any way inferior to the ones listed above. Some probably are, while others may be better than locations listed above. I simply do not know. I have not been in these facilities or heard from enough people I trust to confirm details. If you're looking for colo and have the time to conduct a full search I'd consider every facility. Feel free to send me details of what you find.)
