[OSM-dev] Tile acess statistics?

[Stefan Keller]

Hi

I'm also interested in tile acess statistics of the Slippy Map (or other
well known renderers with worldwide coverage)
It's for the purpose of getting evidence about regional and local use of
OSM.
It doesn't need to be realtime but shouldn't be older than one year.
Any hints?
