In T199816 we deprecated status.wikimedia.org, and replaced it with a static HTML page that points users to a grafana dashboard. This is a reasonable intermediate step, but is not a particularly user-friendly way to indicate when a particular wiki, group of wikis, or partial functionality is unavailable.
We should implement a status page that gives users information about when some/all functionality is impacted; and displays that information in a user-friendly and easy to understand way. Ease of use and accuracy are very important and should be taken into account by any implementation. (These were the biggest issues with the prior Watchmouse implementation, and resulted in that implementation being removed.)
