Realtime might be possible in Europe - We have huge areas in the World
where realtime is simply impossible due to missing IP infrastructure.

And mapping a disruption/destroyed infrastructure is not only a matter
of mapping resources but also whether the data is still usable.

If there is a local divert - dont delete the bridge if their will be
a new one within e.g. 6 Months. The map data with the bridge intact
are still usable and fine.
