Is the Googlebot IP only from the USA?

[serenoo]

I have this problem:
[webmasterworld.com...]
and I decided to solve it by going on my cpanel account and deny all ips, that visited my website, from Russia and Ukraine. Now I have a doubt: Is there a chance I banned the Russian googlebot ip?
Or is googlebot ip only from USA?
Probably this is a stupid question and I became paranoid about any update on my website that could hurt Google.

The official Googlebot is based in California according to Google. The human raters however may be anywhere on the planet so blocking an entire country might cause a few of them to give your page a *did not load* rating. I imagine that if your site gathers enough of those it might impact your rankings, only Google knows for sure.

Google's method for webmasters to verify googlebot as being authentic rests on a reverse and forward verification of the IP address.

All the IP addresses that verify in this way are Mountain View CA. See How to Verify Googlebot and Avoid Rogue Spiders [webmasterworld.com]

You can either find the IP range of rough websites and deny access, or you can switch from a server based analyzer to page tagging–based analytics service (like Google Analytics etc.)

"You can either find the IP range of rough websites and deny access"
(For some ip there is a range, for others there is a fixed ip)
Levo, isnt't that what I did?

You're right. But make sure to find and block the IP address/block of the server/datacenter. AFAIK Google and/or raters don't use those IP addresses.
