I had always supposed that the IP routing tables were so fixed that if I  
accessed a given IP from within the UK, the packets would go to a  
different physical place that if the same IP were accessed from within the  
US.

For sure, I have noted that when I access google.com, it somehow manages  
to serve me with adverts for UK suppliers, and also frequently end up  
finding that I am speaking to google.co.uk.
