People on SEO and webmaster forums have noted for years that you might see different results if they are being served from different data centers. You might receive results from different data centers because you’ve changed locations, or because one data center is busy, and your query has been routed over to another one. The “reasons” for the differences are often cited as one data center testing a different algorithm or having been updated in some manner while the other isn’t. Another possibility that I haven’t really seen mentioned is the possibility that different data centers may optimize their search results based upon making searches better for people located closer to each datacenter. This patent filing describes how that might be done.
