The OpenStreetMap.org website and mapping API will be read-only / partially unavailable on the 26 September 2024, from 20:00 to 21:00 (GMT/UTC) due to essential server maintenance.
Extra note for community.openstreetmap.org users. It is likely that you will NOT be able to login during the maintenance window. If you login BEFORE the maintenance or after the window all will be good.
