If your videos are acceptable to Vimeo (they have anal TOS but great technical platform) then I recommend at all times upload duplicates to Vimeo (and someone else). Then register your own URL shortener domain (such alex.je or whatever) and send links to your video through your own shortlinks, such as: alex.je/2013
Trusting your business to single platform provider - no matter how big - is disastrous.
With planning like above you'd be back in business in no time by flipping redirect URLs to your videos at secondary provider.
