Usually I post to slrpnk.net and they are currently on 0.18.5. None of my posts/comments (2 posts, 1 comment) are federating.
Just letting you know if anyone here is posting to non-updated instances, it's possible they aren't going through. Yet completely possible they are. Who knows with this federation business.
I'm going to go to the Winchester Engadine Maccas, grab a schooner shit my pants and wait for this to all blow over.
I made a post at 0.19 (I believe) to slrpnk 2 days ago, but since the 0.19.1 it fails. Does the 2 days relate to what you noticed?
Edit: seems restarts has something to do with it. Version numbers may not as the bug is present in both 0.19's
