Incident
A small percentage of users are experiencing issues with Slack.
On May 23, 2023 between 8:38 AM PDT and 9:44 AM PDT some users were unable to send and edit messages, load threads, join channels and create group DMs. Our investigation uncovered that a recent code change we made had caused an overwhelming impact on our databases. We rolled this change back and temporarily redirected user traffic as our databases recovered. Once we rolled back the change and our databases were in a healthier state, the issue became resolved for impacted users. We will continue to implement new ways to detect issues like this early-on. Thank you for your patience while we investigated and resolved the issue.

Some users may still be experiencing trouble in Slack, specifically with sending and editing messages, loading threads, and joining channels. These features are working slowly for some users, and not working at all for others. We’ll continue to provide updates as we know more.
