commit 7c59c7c3ca336822aa424b31ae4d5eb6383c8026 Author: Karsten Loesing karsten.loesing@gmx.net Date: Sun Jan 10 09:48:50 2016 +0100

Stop returning code 500 when serving stale data.

Until now, when the hourly updater has not run for 6 hours or more, the server responds to all queries with a 500 Internal Server Error. This seemed to be a good idea, because users would tell us when the hourly updater was broken and we could fix it. But actually, these 6 hours were chosen arbitrarily, and each application should decide for itself when it considers data as stale. That's why we're taking out the check and stopping to return a 500 status code because of potentially stale data.
