Now I could be wrong on this, but I believe that's at the EXTREME end of things, I would say with the way DNS is updated now it usually takes under an hour at most. At least that's my personal experience.

Thanks for clarifying :-)

But under an hour still kills the concept of location based services.

Under an hour still works for 'who is in London for dinner tonight'.
