Having just fired it up after getting home from work, it works fine for me. Here's the link again, although it's on the first page.

Also, since this video is so long one note about Twitch's archive policies needs to be known here. Twitch deletes all archived videos after 10 days, and the only way to preserve it is for the broadcaster to make it into a highlight. From what I can tell they haven't done that with any other stream so I don't expect it here. That means if you plan on watching it in parts (it is almost 8 hours long after all) just try to keep that 10 days in mind.
Of course, that will be irrelevant once somebody (probably Hoz) uploads it to Youtube.
