Support map.project-osrm.org
Separately, I would like to note that this is one of the few routers that has a map with debugging information, which is useful for cartographers: https://map.project-osrm.org/debug
What debug info should I see here? Other than speedlimits and ZYX Tileinfo? I don't see a router.
Speed limits and the presence of roads in the router graph are debug info.
Speed limits != maxspeed=* in OSM, and calculated from other tags as well.
If the road is not on this map, then it has incorrect tags. For example, roads often disappear from the graph when the cartographer forgot to remove construction=*
The map also highlights isolated subgraphs in magenta
upd: Also displayed restrictions on the turn
