hi.wikipedia.org (Hindi), could be made to points to an Indian Cluster
ja.wikipedia.org (Japanese) ... to an Asian cluster.
So we actually want different domains :b
That's not how we load balance stuff right now. All the
*.wikipedia.org and *.wikiwhatever.org domains are CNAMEs all pointing
to
text.wikimedia.org , which in turn is a CNAME for either
text.pmtpa.wikimedia.org or
text.esams.wikimedia.org , depending on
your geographical location (or, to be more precise, the location of
the DNS server you're using).
In other words, we don't load balance based on a wiki's language, but
on the user's location. Someone visiting
de.wikipedia.org while in
Japan hits the Tampa cluster, and someone visiting
ja.wikipedia.org
while in France hits the Amsterdam cluster. In fact, when British and
American users view
en.wikipedia.org, they view the same wiki through
different clusters.
