November 2013 server maintenance
NOW COMPLETE maintenance on 27th Nov 2013
Old information
On 27th Nov from 17:30 the primary database server will be unavailable due to maintenance. Sysadmins will be performing hardware upgrades to the database servers
Additionally we will be operating with reduced front-end servers from16:30 (one hour earlier) but this is not expected to cause any visible change.
End of maintenance window is at 22:00 (GMT / UTC). Update: Write access seems to be restored since 19:19.
Actual service times may vary within the service windows described above.
What is affected?
The API and all DB dependant services.
The API will be read only, meaning you will not be able to use OpenStreetMap editors to make changes to the map data (They use the API). You will be able to download data, but not upload changes. You may be able to use JOSM or Merkaartor and download some data to edit offline, however this is for advanced users only, since you will need to take care with conflict resolution when saving your changes after the API comes back online. The chances of this being problematic depend where you are editing. In general it is recommended to cease editing until you can upload.
The OpenStreetMap website will be largely unaffected, however you will not be able to login, and no new diary entries or GPX traces can be posted.
Diffs generated during the read-only period will be empty. External services using diffs may be affected by this.
Unaffected
The plan is to keep the website available. You will also be able to view diary entries and GPS traces, but you will not be able to login to edit them. Likewise you can view data on changesets and elements. The Export sidebar will work.
The tile server will continue to serve tiles to all other applications and websites during the work. No work is planned for the 'standard' OpenStreetMap tile server. Maps will continue to display on other websites (No planned downtime, but note that we do not guarantee availability of the tile server even in normal circumstances. See Tile usage policy) Likewise other 3rd party tile providers will be unaffected.
Also unaffected:
- Nominatim (search)
- wiki - This documentation site.
- Development servers, SVN & git, trac
- IRC
- forum
- help.openstreetmap.org
- donate.openstreetmap.org
Unforeseen problems
As mentioned, actual service times may vary within the service window described above. In the event of unforeseen problems in the maintenance work, downtime may extend beyond these times, or the plan may change. In particular the plan is to keep many services available read-only, but unforeseen problems could cause complete outage (as they may at any time in fact)
