I experience that changes in OpenStreetMap are not reflected in map tiles and routes even after several weeks.
This is best shown with OpenStreetMap.org and open.mapquest.com side by side. The path going from (2) to (6) in the left part of the screenshot was deleted 17 days ago on OpenStreetMap.org. The screenshots are taken around 55.695890, 12.566772.
How often is the MapQuest data updated with changes from OpenStreetMap?
Are the current delays a temporary glitch or something we should expect?
