I am getting fantastic results on the DP keyword tracker but cannot find anything like those results on any of the DC's I have checked (including any on mcdar)? Is it using a particular DC or is something strange still happengin at G?
I've seen some unusual results in the DP keyword tracker, but also in my home-grown tool that simiarly used the Google API ... so my guess is this is more API related.
It doesn't use any specific data center. It uses whatever data center Google routes the requests too (just like if you go to www.google.com).
