Toward faster international server selection using clever DNS.

Show all headers | View raw

When you type google.com you get sent to google.ca if you live in
Canada.  I presume this works by your request going to google.com in
the USA, where it then figures out you are from Canada and sends back
a redirect,  then you resend your request to google.ca a server in
Canada.  Is that correct?

blogger.com (owned by google) has just started doing this variable
suffix thing too.  All kinds of large companies use this sort of
logic.  Sometimes you must manually select your region.  It strikes me
as inefficient. If the head office is in Taiwan, it is quite slow
(e.g. motherboard manufacturers).

What should happen is the DNS routers in Canada should direct
google.global requests to google.ca. and in the USA to google.com.
You should be able to bypass the country server selector with a
specific google.ca request.

Does it actually work roughly this way already? if not, why? It is
just the inertia holding back extending DNS software in all the
world's servers?

If it does not work this way, or when the server uses the redirect
method,  it suggests I can be kind to my clients in my JSP (the Java
topic tie) by localising links to global enterprises in the generated
HTML so they go directly.  

For example, on every page in the Java glossary is a link to google
that lets you find more information about the topic of the page. This
link could be localised if I were using JSP to dynamically generate
the page.
