Where can the bit.ly/shiny-quickstart-1 content be found now that Bit.ly has blocked it?

Today, 6/4/22, I tried to access the bit.ly/shiny-quickstart-1 content, only to be told by bit.ly that they had blocked it because of security concerns.

Would anyone know where that content may be found now?

what content was there ?
If you are looking for a resource from which to learn shiny, theres probably no better than : Mastering Shiny (mastering-shiny.org)
