We've talked with the VOC, and they helped us find a great solution to make the livestreams on streaming.media.ccc.de stable. We will keep this livestream running in any case, but you can now use the much greater comfort of the media.ccc.de player :)
Unfortunately our C3 VOC setup has some issues with streaming this year. To allow you to see the talks anyway the Chaos-West stage FOH team has quickly set up our own streaming solution as a emergency backup. This setup is independent from the VOC and we hope that it works if the VOC stream gets stuck. We thank the VOC for all their work and hope that we will be able to resolve the issues quickly!
