Norwegian IT publication digi.no published a story today on the Opera Mini servers. It gives you an interesting look at the Opera Mini server park. …
In the image gallery there is even a video there with a spinning globe showing real-time Opera Mini usage:
An interesting fact which is revealed in the article itself is that Opera Mini apparently makes up 10-20% of foreign traffic in Norway. And Opera Mini traffic increases by 20% monthly.
Hopefully it might be possible to ask for digi.no's permission to translate the article, as there quite a few interesting pieces of information there for hardcore geeks.
