Camunda best-practices Authorization Required

Most recently, I read the “best-practices” manual.
Why now when clicking on the link https://camunda.com/best-practices-stage/deciding-about-your-stack/ authorization began to be required?
I get error 401 …

take stage out of the link and it should work
https://camunda.com/best-practices/deciding-about-your-stack/

Look at the main menu of the page at https://camunda.com/best-practices/
Each menu item in its url contains “stage”. Links are incorrect. Please fix it.

Thanks for the hint - we recently updated the CI/CD process and seem to broke this. We will fix it asap.
