I'm seeing messages double post for some reason, both ones I send and ones from my coworkers. The 2nd message fails the first time. And the occasional connection error.

Yes, slack is intermittently down for me and the rest of my company. It's intermittently losing messages, failing to load new ones, and showing error pages :-(

Yes, briefly for me. I also lost access to Fastmail.

Yup, I just checked in multiple workspaces and I was unable to connect in all of them.

Yeah, just ran into a few blips. Seems to load intermittently.

Yes, getting a bunch of retry and messages failing to send.
