I prefer a diagram on a company wiki that contains only text boxes and connections. Accessible and editable by anyone in the browser (we use draw.io plugin for confluence). I accept that these diagrams will always be out-of-date and therefore try to keep text and details to a minimum. I think of it more as a pointer for where to "dig up" a piece of the system or who to ask, to use your metaphor.
