How Google Data Centers Work
Friday, June 20th, 2008If you didn’t already know Google has many data centers that run their index at any given time. They use different data centers to show different results. Some one on the East coast might see different results than someone on the West coast. Even using the next button on Google might take you to a different data center. Google decides what data center provides what result at any given time. If someone is aware of the different Google data centers IP address’s then they can poll each data center separately.
With the upcoming Big Daddy update Google has said that they are targeting these types of algorithmic changes:
* Canonicalization - How the engine decides what url’s reside in the engine.
* 302 redirects - Some developers have tried to spam the engines by serving keyword rich pages.
* Duplicate Content - Would be the same information at different locations.
