Webwalla,

I am too lazy to find it...sorry.

But I found a replay from Vanessa Fox when someone asked why his site after moving to a US hosted server do not show on Google UK.
In her answer you can see that Google do determine rank according to your server location (as one factor out of many)

"the move to a US-based server potentially why your site is
no longer in the UK listings."
&
"For .com domains, we rely on the location of the IP address. My best
suggestions (although either may be difficult) would be to either
switch the server back to a UK-based IP or move your site to a .co.uk
domain (and redirect the .com to it). "
