Voting history through timeline is functional on non-deleted question using the address of:
There is one thing that may trip things up, however, and that's that you must specify a question ID. This is a bit different than what one might think sometimes because for example, if you want to see the revision history of a post, you can specify an
<answerid> to look at an answer. The timeline, however, only works when looking at questions (it will tell you the votes for all answers to that question, though).
If one keeps that in mind, it should work as long as the question is not deleted. It is currently not possible to view the timeline of a deleted question.
For those who are capable of it, this Meta Stack Overflow post contains a couple scripts and such that you can implement that will provide a link to the timeline view without requiring URL manipulation.
