Google Search Working
Occasionally, fluctuation in search results is the result of differences in our data centers. When you perform a Google search, your query is sent to a Google data center in order to retrieve search results. There are numerous data centers, and many factors (such as geographic location and search traffic) determine where a query is sent. Because not all of our data centers are updated simultaneously, it's possible to see slightly different search results depending on which data center handles your query.
