Any one know how different "Blogger/blogspot" domains work?

While looking at my sitemeter stats, noticed some domains which I never seen before.

First, there's this one looks like from France "http://new2objectivec.blogspot.fr/"

Then this one from India "http://new2objectivec.blogspot.in/"

This one from UK "http://new2objectivec.blogspot.co.uk/"

This one from Germany? "http://new2objectivec.blogspot.de/"

Also, recently, when I entered my domain name as "http://new2objectivec.blogspot.com/", it automatically redirects to Australian version: "http://new2objectivec.blogspot.com.au/"

I guess from Blogger/blogspot point of view, by redirecting traffic to local servers would be faster than all coming to one central site. I know there's this company called Akamai which installs lots of cache servers in different countries and automatically caches the content of it's client's web site to these local cache servers to improve the performance/customer experience. Probably Blogger/blogspot is doing the same thing?
