I've done enough trouble shooting to know the problem. The problem is the AH international connectivity.
Local is always perfect: http://www.speedtest.net/my-result/4839372999
International on the other hand is never consistent. Can see it on FTP downloads but more frustratingly when watching Twitch. Kind of hoping pointing out the issue when it happens would help.
So for example today at 13:28 I went from streaming source perfectly all the way down to medium (even that is actually buffering.)
There definitely shouldn't be any international throughput issues, all looks healthy from what I can see.
Can you let me know what your throughput is like to this file please?
