Yesterday, users of mstdn.social instance lost their connections to artists at mastodon.art instance ( src: https://framapiaf.org/@Curator@mastodon.art/110570978375947500 ). I hope giving visibility to this issue will help them to restore the broken bridges.

We're no longer blocked by mstdn.social, but I don't know if that's subject to change. Unfortunately, when an instance suspends another instance, all follow/follower relationships are immediately broken and aren't recovered by un-suspending, so you will have to find and re-follow your connections there.

@davidrevoy it was resolved at 3pm BST yesterday right? As far as I know, curator and one other account is blocked, that's it.
@experiencersinternational @davidrevoy the follows between the two servers don't come back when an admin unblocks another server. They stay gone unless people manually refollow
@eniko @experiencersinternational @davidrevoy Yep, lost 400 connections when Mastodon.nz suspended Mastodon.social last month.
