Since the last additions to our OpenStreetMap tile serving network in December, there has been a lot more server set-up going on.
The German tile cache server tabaluga is now retired and is no longer serving tiles. This may sound like bad news, but quite the opposite! Tabaluga has been replaced with a new server, katie, which has taken over its job.
The new tile cache server katie is still located in Falkenstein, Germany, and still hosted by Hetzner.
More good news: There are two tile cache servers in Germany now!
The second tile cache server, konqi, is located in Jena, Germany, hosted by EUserv.
The Russian tile cache server gorynych just had a memory and SSD upgrade, and with this it can deliver even more content.
There is another new server in Hungary. With this Hungary becomes one of 12 countries hosting OSM CDN servers.
Tile cache server sarkany is located in Budapest, Hungary, hosted by szerverem.hu.
With all of these, the CDN (Content Delivery Network) server count comes to 16 active servers.
Tabaluga was running, thanks to Freerk Ohling, at Hetzner since May 2013, and served its last tiles in January. Freerk approached us back in April 2013 to suggest we implement EDNS client subnet support (implemented in December 2014) and to offer us a sponsored tile cache server. Now he has also kindly sponsored new tile cache servers in Germany.
Tabaluga primarily served traffic to visitors from Germany. Approximately 56 million map tiles per day. (avg 652/sec, peaking at 1245/sec). Serving close to 1TB of data per day. It was the highest traffic OSM tile cache server.
OpenStreetMap tiles are free for everyone to use, but should be used with moderation. If you are a high traffic site you should look at switch2osm.org to find out how to use the data and keep the tiles available for everyone.
The OpenStreetMap Foundation seeks additional distributed tile servers. If your organisation would like to donate a tile server and hosting, please see the Tile CDN requirements page on the wiki. You can also support OpenStreetMap by donating to the OpenStreetMap Foundation.
The OpenStreetMap Foundation is a not-for-profit organisation, formed in the UK to support the OpenStreetMap Project. It is dedicated to encouraging the growth, development and distribution of free geospatial data for anyone to use and share.
