Geolocation of Google Compute Engine Servers?

Question

When creating a new instance, GCE cloud allows choosing among three regions: West Europe, Central US and Asia.

I'd like to know exactly where the instance is allocated, e.g., know the precise coordinates.

GeoLocation databases point all GCE-allocated IP addresses to Mountain View, CA (Google HQ). Is there a way to find out the correct exact location?

Answer 1

Based on ping times and traceroutes, I've made some educated guesses:

• US Central 1: Oklahoma
• Europe West 1: Ireland
• Asia East 1: Changhua County, Taiwan

Answer 2

This page shows the physical locations of Google's datacenters: http://www.google.com/about/datacenters/inside/locations/index.html

But no precise information on which datacenter houses which GCE Zone.
