I second that. 15 and 17 thousand km in a "straight" line.

Origin (Varnish 0): Sydney, AU
Varnish 1: Chicago, US (Rackspace ORD1)
Varnish 2: London, UK (Rackspace LON3)

We had London fetch content from Chicago and, that node being sick, London would fetch from Sydney directly.

This setup has since been replaced by a brand-name CDN but it served us very well for 2 years.  In fact, it worked so well that we didn't see a performance improvement (latency) when moving to a CDN (we still went ahead due to other reasons).
