i'm amazed that no one has even bothered to look into this from sony or twitch, i spoke with CS and they told me to do this that and the other and then told me ring tech support so i wasted ages talking to someone who doesn't have the slightest clue of what to do. Its been 6 days its been down now and this is beyond a joke, i've had to resort to uploading videos to facebook downloading them and then uploading them to youtube just to keep my followers happy.
Just called Support. They took notes of the issue, but, at the first tier level, there's not even a disambiguation for that code. All my troubleshooting points to an issue with the PSN link to Twitch, but that's only a theory. Likely they're testing or optimizing the servers for 720p and archiving as previously announced.
Annoying, but understandable.
