This is a very simple cache for a selected list of calendar feeds hosted on radar.squat.net. Radar is doing an amazing work for years. But the servers have some uptime issues (see related blog posts). This server regularly retrieves the latest calendar feeds (ics files) and makes them available here unchanged. This is intended to reduce the load on the Radar infrastructure. You can use this stable version of the feed in your application.
The feeds listed here are updated every ~15 minutes (if possible). If you would like to have additional feeds hosted here just contact us at admin@mg-berlin.org
