Bit pedantic but FYI it appears this host is down or the webserver is. Wouldn't normally care but it is still referenced on your production site. Speedtest for example: https://rawgit.com/nplab/WebRTC-Datachannel-Playground/master/speedtest/speedtest.html
<script type='text/javascript' src="https://webrtc.nplab.de:3001/socket.io/socket.io.js"></script>
