[OSRM-talk] Colombia - Tunel de la linea

Hi Carlos

For routing.openstreetmap.de (the one used on osm.org), it takes about
3-4 days to calculate all the graphs (car, bike and foot, worldwide).
The timestamps can be found here

For understanding why a route does not work, I would recommend to have a
look at the debug view
https://routing.openstreetmap.de/debug/car.html#12/4.4794/-75.5224 the
pink highlights are showing routing islands, meaning the router detected
that it can't get to those streets from the rest of the network.

Another strategy is to drag around the start or end marker to see at
which point the routing is hitting an "obstacle", usually some error in
the tagging or an unconnected road.
