A day or two back a lot of smaller instances were temporarily defederating from the large instances to clear a message cache that was slowing down the whole fediverse, then refederating again. Just growing pains stuff on a system that never had to scale like this before.

I’m willing to bet they were just caught up in one of those purges.

Huh, interesting that I come here on my programming.dev account and only see 2 of the comments that I saw as OP on my lemmy.world account. I wonder if there’s a lot more defederation going on than I realized…
