The Powerdns geo backend as mentioned by the article is used by wikipedia among others. I have some additions (e.g. Google Public DNS), see the files at https://gist.github.com/dgl/8344c3ebe405a1400e2d https://gist.github.com/dgl/8344c3ebe405a1400e2d (which also has the rsync location for the original).
