Excellent! What I saw this morning was that comment federation seemed to be taking between 15 and 20 minutes. As before, I don't know what your intervals are, but I figure you could use that data point to verify/validate as necessary.
But this one isn't. It is quite recent, and I don't know the intervals for shunting comments off to other instances, so it could be that. Edit ~20 minutes later: This one is also federated.
I'll paste you the Fedia and original links to the last comments I've made that don't seem to be federating. The comments are visible at the fedia, but not at the foreign instance. I can see by reviewing these that it appears to be all magazines and all foreign instances, because these are all the comments I've made in the last day or so.
Ernest made a post today, yes, but kbin.social has reached a point which demands a next level of administration (from both technical and non-technical perspectives). While I want that project to thrive, there is writing on the wall which unfortunately cannot be ignored.
Growing pains are to be expected. You're probably aware that some people (myself included) are shifting here [from|in addition to] kbin.social; that extra load probably doesn't help.
