Dang, I was up at 3AM in the night waiting for the @ivory beta but their post with the link showed up 13 minutes delayed on my end. No luck for me.

Mastodon isn't good at propagating posts in near real time.

@simonbs The reason it doesn't show up on tapbots.social is because the post is only visible to followers. When you are viewing tapbots.social, you aren't logged in to an account.
@simonbs For what it's worth, I saw it at basically the same time and lots of other people also say they didn't see the post until around 12-13 minutes after the hour. I'm guessing that was caused by tapbots.social falling over rather than a Mastodon federation issue.
