They could mirror it to youtube and keep their own thing as a backup. If anything I trust content on youtube to survive the times better than Mozilla's own service. There have been too many videos going offline because the were on tiny services.
I don't there have been to many videos going offline which I embeded on my own website because YouTube took them down for various reasons.
And my MySpace content is gone, the content from 2004 in my blog is still served without problems. Example: http://jeenaparadies.net/weblog/2004/apr/ersteintrag
It does. But the server is not responding fast enough for me. Both on my home ISP nor the one on my phone. So my assumption is that they have either not enough bandwidth or bad peering with my country.
Here's my bookmarklet (doesn't work on embedded videos in iframes, I assume because of same-origin-policy)
javascript:void%20function(){document.querySelector(%22video%22).playbackRate=parseFloat(prompt(%22Set%20the%20playback%20rate%22))}();
When there's the bandwidth to serve it, air often fails to load fast enough for 1x.
