Not only Google's index is spread over more than 10,000 servers, but also these servers are, as of now, placed in 13 different data centers.
that shows power of linux....
No kidding. I'd love to read about the engineering behind a system of that magnitude.
It will only be a matter of time before Linux becomes a major threat for Windoes operating systems. It is becoming a great substitute for Windows platforms.
