The beehaw.org/sh.itjust.works defederation is really one-way. Beehaw defederated from us after some exceptionally bad trolls were operating from sh.itjust.works in 2023. IIRC, they requested that we also defederate from them to really make sure the split was made. We honored their request.
We would happily reconnect if Beehaw decided they want to federate with us again. If not, then that’s fine; they have a right to associate with whomever they like.
I believe infosec.pub temporarily defederated from us around the same time for the same reason. It was a rough time.

If you want to complicate the graph further, I believe hexbear federates using an allow list. Blahaj, lemmy.ca, and sh.itjust.works are not on the allow list, so they are effectively defederated. I haven’t looked further to see which other large instances may be affected.
