Last night I spent a considerable amount of time going through each country code by hand to determine where G has datacenters. This should help some people for scraping purposes:

.at
.be
.bg
.bo
.bs
.by
.bz
.ca
.ch
.cl
.cn
.cz
.de
.dk

.to
.tp

.co.zw

Just add “google” to the front of any of those codes to get the webpage of the corresponding data center.
