Recently there have been a few issues with OSM updates. It sometimes happened that routing data got older than 14 days. Therefore the whole OSM update pipeline for the routing server got revamped.
Ideally this should lead to OSM data that is not older than 4 days. This means on average most OSM updates should take effect after about 2 days.
Usually there should not be any issues due to this, but if you notice anything weird, please let us know.
