Shiny tutorial slides can't be found

The Shiny tutorial says that slides and code can be downloaded from: bit.ly/shiny-quckstart-1 however when I try that link I get a 404 error from: https://dl.dropboxusercontent.com/u/5896466/shiny-quickstart-1.zip
which looks like Dropbox site.

Am I doing something wrong? Or is the content missing?
