* So that is what inaccessible road is!
Posted by Zkir on 19 October 2012 in English. Last updated on 20 October 2012.The essential condition for a map, to be used in routing, is integrity of the road network. Ideally, there should be a single [strongly connected component] (osm.org/user/DennisL/diary/17853). All edges of the road network should be accessible for routing.
Unfortunately, there are currently 1,000,000+ inaccessible edges (road segments) in OSM data. It looks that fixing them all will be hard toil.
Here is a small tool that can make this task easier:

It works in a very simple way: it displays one of the inaccessible road segments found by OSRM test, and loads it automatically into JOSM for editing.

Currently, inaccessible edges from selected areas (Poland, Finland, European part of Russia, Thailand and Japan) are suggested for fixing. In the near future it will be extended to the whole world.
The utility has user interface in English and Russian, other languages can be added if somebody helps me with translation.
