Ask HN: Is Slack Down?

It's not just you.

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

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

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

https://slack-status.com/ -- no incidents reported at 3:33PM PST

Yes

was down (messages not going through) for me, then web was ok, then all went down, now back up

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

Slack, Fastmail, Claude, Github - all seem to be having intermittent outages and are randomly logging people out.

"Users experiencing issues connecting to Slack and unable to load threads" - https://slack-status.com/2025-05/7b32241eb41a54aa

Yep, I'm getting random issues too

uptime of 100% -- time to update that number :p

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 :-(

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.

Yeah! now I'm Learning How TCP Network is Work. trying to keep sending Messages twice.

Whichever Salesforce employee has their bonus tied to this being declared an incident and not an outage; fuck you.

This has affected critical, operational processes which YOUR sales and marketing teams use in Case Studies[0][1][2] and documentation[3][4].
