9 680 000 000

If I change to English then I get
11,120,000,000

How these numbers differ so dramatically?

Mihkel, I get either 9 or 11 billion on the normal clusters. I don't think it matters on the language, just which data center you happen to hit. I don't know why the numbers vary.

poland:
25,270,000,000 from .com
9,680,000,000 from .pl (for Web)

maybe it depends on which server servs you

Google.es gives me the following:
Web --> 9.670.000.000
In Spanish --> 119.000.000
In Spain --> 62.500.000

Here's a URL that will check a bunch of data centers for you at once. I'm seeing about half 9-11 Billion and half 25 Billion.

BTW Philipp, you should whip up a handy tool do this for you and others ... my guess is they are just doing iframe's with the different results from different data centers/iP's.

Funny, it depends on the language...

google.ro in Hungarian -> 18 100 000 000
google.ro in Romanian -> 9.670.000.000
google.ro in German -> 9.670.000.000

google.sk in Hungarian -> 18.090.000.000
google.sk in Slovak -> 20 960 000 000

google.co.hu -> 18 100 000 000

Slovak rules? ;)
