It's awesome because youtube is (intentionally) annoying, plus, it's nice to give back bugfix/feature patches when someone else (jwz) is kind enough to give their code to the public.
EDIT: Thanks detaro. Link removed. I didn't know it was an issue, and obviously, couldn't see it.

The url I posted and removed still works fine, so long as it's not originating from HN (i.e. 'referer' checking). If you do a quick web search on 'youtubedown' you'll find it.
If jwz is trying to avoid the HN-effect, then sending people via another route won't completely mitigate the problem.
I went ahead and updated the archive.org link. Providing that means HN users don't need to do yet another search and his site shouldn't get hammered nearly as much.
Anyway, it seems to be a static website, and it should be able handle HN traffic for a fairly small amount of effort and/or money.
And it is most amusing.
