Hi,

The data center locations is interesting, but it isn't what I was looking for. I need to know whether Google crawls the web from any IP other than US IPs.

To clear up the second question, let me be more specific:

Let's say Google is crawling a .co.uk site from a US IP address. The site is using GEO IP redirection to redirect all US traffic to the .com site. Therefore, when Google attempts to crawl the .co.uk from the US IP address site it will be redirected to the .com site, never seeing the .co.uk site. Can anyone confirm that this is what happens?

Where does Google crawl the web from? Is it in the US only, or do they do it from a European base too? The reason for asking is for GeoIP redirection. For example, if a website is using GeoIP redirection to redirect all US traffic to a .com site and all EU traffic to a .co.uk site, will Google ever see the .co.uk site?
