I frequently check my ranking on Google at home and at work. But the results I get from each location are consistent but different.

At home, I'm always on page X, while at work I'm always on page Y. When I use a Google Rank Tool, then I'm always on Z.

I'm thinking this is because each of the locations reach a different data center.

I've tried to see my results from different data centers using Google Dancing Tools, but the different dance results are always the exact same as each other, R1, R2 and R3.

Am I right in thinking this is a data center issues? If it is, how can I see how I rank from other data-centers?

Thanks.

check the Ip address and route paths.. it could be a geo target problem...
