Traffic statistics from major ISPs

In the voice world, AT&T, SBC, Bell Atlantic and others have released traffic figures about how many voice calls they handled around New Year's. I have not seen similar data from any major ISPs about traffic volume around New Year's. I know about third-party sites such as Keynote, and MIDS; but they don't measure traffic volume. I'm looking for basic data such as ANS used to publish for the NSFNET. The closest I've found is Abovenet's MRTG pages, but it is spread out over different links and its hard to aggregate the numbers without double counting, or undercounting. I know several major ISPs collect the data internally, but haven't released it like the voice side of the house.
