I have some sites that ranks for main keywords very different on couple of data centers. Example my main keyword ranks here http://64.233.179.104/ on 7th position and here http://64.233.167.99/ is not in top 100. My site is probably in sandbox, it is old 4 months. Are data centers going to synchronize when site ends with sandbox ? Is it possible that site will rank the same (5-10 places different) on different data centers ?
