Hoi, What we need is a database with a robust and fool proof synchronisation process. Latency is important when all the databases have to be synchronised all the time. When articles only need to be the latest when they are readied for editing it is less of an issue. When the data is shared over many computers in for instance a peer to peer network, the real cost can be high but when the cost is shared by volunteers and organisations volunteering it is no longer much of an issue for the central organisation. Databases of such a design are not that rare. There has been research on this for Wikipedia usage in Amsterdam where it is considered feasible.

Today, this is a computer science solution, not an operations solution. The Foundation doesn't exist to be a testbed for making computer science technology operationally mature. -- -george william herbert george.herbert(a)gmail.com _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l

If I remember correctly, a backup of database is in a public folder, so anyone can download it. Some people do it, to run analysis and do some interesting science/tech projects. If the FBI and the Interpol put the wikimedia people in jail (thats not going to happend), anybody in a country withouth extradition treaty to USA can recreate it. So, the wikimedia organization can be killed, but the data is public and mirrored "enough" so probably can't be killed as easy.
