Hi all, After the previous thread, I ask out of curiosity, what if there were just a small number of servers spread around the world, not owned by the WMF. Something like:
- Users can access en.wikipedia.org, en.wikipedia-brazil.org,
en.wikipedia-japan.org etc interchangeably
- Each site is a complete copy of the database, and capable of serving
independently
- Every change on one database is immediately replicated to the others
- To make this worthwhile, all the servers except the original are
owned and operated by third parties on a sponsorship arrangement, presumably meaning they get to discreetly stick a logo somewhere

As far as I know, you've just described (more or less) the MySQL Cluster database: http://mysql.com/products/database/cluster/
