After the Apicalipse there was a website where you could see which instance de/federates with others, as a map. It’s url was https://lemmymap.feddit.de/ but I guess it went down with feddit.de I found even a screenshot in a thread:

Currently with the instances button you can see defederation from one direction, but not from the other, e.g. if an instance is defederated by a lot others you can’t see that easily.
Does something like this exist?
The source code for it can be found on https://codeberg.org/wintermute/lemmymap/src/branch/development
But with Wintermute going missing and feddit.de shutting down is has been shut down as well.
It was a nice map. If it still works I will try to redeploy it.
Edit: This is an early prototype of the lemmymap, not the latest version of it. I don’t think it’s worth to deploy. I may recreate it from scratch in my free time.
LOL, at a quick glance one might even be able abuse a scheduled job on free-tier GitHub runner for the data update and host it statically on GitHub pages.
“Serverless for the poor”
and you will do it?
Someone could of course run it locally and take a screenshot for everyone :)
