We have 45 Mbps from XO in our downtown Chicago location in the financial district. We have asked for IPv6 every month for a while, and keep hearing "maybe soon" and not much else. Unfortunately, if we can't get it in that very competitive and dense market location, I doubt they offer it anywhere.
Note to anyone clueful from XO listening: the RFP is going out next month, and IPv6 transit is a MUST.
