Yes, and apparently it's impossible to post the status link on HN anymore. If you post it directly, you get an 11 month old thread about slack being down. If you post it with an edit to make the URL unique, you get a "dead link" error.

I particularly like: * Threads, direct messages, and channels are currently not loading

.... what else do I use slack for?

I am also amused that they have "100%" uptime for this quarter, and all services report green, while my Slack won't load at all.

Yes, there's an ongoing incident. See: https://status.slack.com/2023-01/70633bef2f8b2fd1

There appears to be a spike in reporting [1]

Baseline: 1 Reports: 817

Yes. https://status.slack.com/

Having issues opening and reading threads.

Yeah I can't open any channels.
