You could search the database for 'google datcenters', but, a quick summary, it used to be that the eight datacenters were google. So when you search google, you would be getting info from one of the datacenters.

However, after this dance it appears that the eight of them aren't live anymore, I think it's five of them, as something different seems to reside on -sj, -in, and I guess another.
