At least for your instance, or for looking one instance at a time, you can see which instances they federate and defederate with by scrolling to the bottom and clicking “instances”
Or go to the url of the form “<instance domain>/instances”
I saw that, but I thought beehaw still defederated from Lemmy world and shit just works… They have them listed as federated
They show up in the “blocked” category on https://beehaw.org/instances
I’m no expert here, but so far the only way I’ve seen is to go to /instances from whatever server you inquiring about.
Such as, lemm.ee/instances
It’s cumbersome in that you have to scroll past a massive list of federated instances (across the whole fediverse, not just lemmy), but you’ll eventually get to the list of defederated instances at the bottom.
I’ve been curious myself tho, if there’s a way to directly see what/if any instances have defederated from yours.
You can look at the /instances page for any instance you want. https://lemmy.ml/instances for example.
I’m still trying to understand all this. I thought all instances “see” (federate) each other. If they can defederate (block) others from seeing an instance, isn’t that going to make discovery a problem? Wouldn’t that also mean I need to create a new account just to see that instance?
Defederating only affects your instance and the other one, so it only affects users on your instance and on the other one (who cannot see content on your own). To get around it requires another account on an instance that has not defederated.
Even aside from differences in opinions, there are very valid reasons for defederating. Some places do not control spam bots, for example.
Most instances default to federating with any instance they find out about, but there is also the ability to make this a whitelist instead and only federate with specific servers.
