Ping triangulation

They use the ping times to figure out which server would be closest.
All the servers are not located in the same place. The idea is that
european users may receive better service from a european server.

The network topology and geography does not match very well, I would guess
that the network center of Europe is likely to be somwhere on the US
Eastcoast.

Only Stockholm have multiple international E3 links....

There is more than one 45 Mbps circuit into the UK carrying Internet
traffic.

There is still a rather high bit of latency to cross the Atlantic. Not to
mention that within Europe, not everyone has an STM-1 backbone. I'm under
the impression (anyone feel free to correct me :), that the majority of
the infrastructure is based on multiple E1s with some E3 connections and
perhaps a few SDH links. One could probably take this picture and copy it
a few times to represent several other countries and/or whole continents;
remove pieces and get a picture of even more countries.

Distributing web servers to remote corners of the world can only be
characterized as a good thing. Not to mention the added value that is
gained in localized content *and* advertising. If the end-user is
shuffled to a 'local' server rather than the 'master' server, the end-user
is theoretically getting a higher bandwidth connection, perhaps content in
his/her local language and perhaps directed marketing.

If traffic is to be moved away from exchange points, a good way of doing
it is to move the content. Developing a mechanism for end-users to access
that content transparently around the world is another discussion
entirely.
