Hi Didier,

I'm getting the same kind of result of about 503 km on a custom server 
set-up with *only* the french road network. But if you look closely at 
the 379 km route you get from the demo server, you'll see it goes a long 
way through Switzerland.

My guess would be the second option (data mismatch), with the additional 
bias of a missing country! ;-)

Best,
Julien
