How 'Powered by Google' is Alexa

really really old stuff

[Powdork]

Checking my site on Alexa I am finding really, really, old results. Whois data from at the latest September 2002, link relationships from the same time frame (this search has the powered by Google logo right next to it). The 'People who visit this page' stuff seems right as does the DMOZ (or is it Google directory?) data.
What of their info comes from Google and how is it updated.

I *think* the only 'powered by Google' stuff is the SERPs and the cached versions in the SERPs. Looks to me like everything else comes from Alexa and Wayback.

Alexa's got a screenshot and traffic data of our site from a year ago.
