I think it's tying for shortest - bit.ly will allow you to create j.mp URLs via their API (not sure if you can do it without the API)

  Although j.mp frequently doesn't work. Clicking the j.mp links often fails, at least on my computer.

  You can just replace any "bit.ly" with "j.mp" and the url should work.
