I know about https://<home_instance>/instances, but this only shows which other instances my home instance has defederated from. To check which other instances have defederated from my home instances, I would have to check https://<other_instance>/instances for each and every other instance, which is not feasible.
Is there a one stop shop for checking which other instances have defederated from my home instance?
I've tried searching for such a tool, but most search results are about https://<home_instance>/instances. I've also seen mentions of https://defed.xyz/, but that site doesn't seem to do anything - when I visit that URL, all I see is a broken image placeholder.
Thank you!
