This upgrade work is complete. The planned downtime has ended. Servers were brought back on the Saturday 3rd as planned.

Original information (old)

The Sysadmin team are upgrading the Database Server's RAID storage on the 2nd and 3rd of July. The API will be unavailable for live editing for the duration of the upgrade.


  • 1st July 21:00 (GMT) - API + www goes readonly.
  • 2nd July 13:00 (GMT) - API + www offline.
  • 3rd July Afternoon (GMT+0) - API + www return.

Initial Maintenance Announcement

API? www? What does this mean?

During the downtime you will not be able to use OpenStreetMap editors to make changes to the map data (They use the API). Initially it will be read-only. During that time you'll be able to download areas of data, but not make changes to the data. On 2nd & 3rd July while the main work is carried out, you will not be able to download data either.

The only way you might work on the map would be to use JOSM or Merkaartor and download some data to edit offline. If you are doing this, you may need to take care with conflict resolution when saving your changes after the API comes back online.

The OpenStreetMap website will also be affected. The plan is to keep the front page map display at http://openstreetmap.org looking similar to normal. The Export tab will also work, but other areas of the site will be affected. You will not be able to login and view/upload GPS traces. Things like user diaries, user edits view, changesets and element browsing screens, will all be affected. All of these will be read-only initially (no new diary entries or comments for example), and deactivated with a holding page during the main work on 2nd & 3rd July.

External services using the API will likely be affected by the API downtime. This may (or may not) include things like tiles@home and XAPI.


The tile server will continue to serve tiles to all other applications and websites during the work (Both mapnik and osmarender layers) and so maps will continue to display on other websites such as http://www.informationfreeway.org/ (No planned downtime, but note that we do not guarantee availability of the tile server even in normal circumstances. See Tile usage policy)

We have a development test server at api06.dev.openstreetmap.org which has some test map data in some areas. For example you can do Map requests such as http://api06.dev.openstreetmap.org/api/0.6/map?bbox=-1.539,51.847,-1.421,51.903 This is not real map data, but the API may be useful to develop against while the real API is offline. Anyone developing those kinds of applications/services should be aware of our API usage policy.

Also unaffected:
