Slack seems to have some issues because of that - I'm not sure if anyone is receiving messages, as it became completely silent for the last 15 minutes or so.
Edit: Restarting Slack does update the edited messages.
Edit 15:24 CET: Slack is back up.
- edits failing or working with big lag;
- "Threads" view slow;
- can't emoji-react;
- can't upload images;
- people also say they can't join new channels.
