Different Google Search Results

Google must be built with a massive amount of networks of servers. I searched at my home, and all my 3 blogs have been updated with information of backlinks. However, when I went to my office and did a search, the backlinks information was not available. So most likely I was connected to 2 different Google servers, and 1 had updated with the blogs links information, and the other not yet. It's interesting to know how Google handling such a vast amount of information.
