@dumpsterqueer @Claire the big 3.4.6 change was something with the JSON-LD, maybe that's messing with things?
@meena @f0x @Claire it would make sense based on the symptoms i'm seeing though: the fact that this instance can still communicate with instances it was already federated with, even if those instances are running newer versions (without a dereferenceable instance actor) can be explained by the fact that gts.superseriousbusiness.org already has the actor keys cached in the db, so it doesn't need to look them up, whereas a new instance does (and hence fails)
@dumpsterqueer @f0x @Claire what if the key changes?
or is that not defined in the spec?
@f0x @dumpsterqueer @Claire *mumbles something about backwards compatibility*
