Some users may be experiencing general degradation issues that cause actions within Slack to fail.

Issue summary:
On April 18, 2024 from around 9:00 AM PDT to 10:02 AM PDT, an automated monitoring system detected a high level of errors and backend database timeouts. We determined that some users may have experienced temporary service degradation and failed actions related to loading DMs and channels. Out of an abundance of caution, we began our incident response processes.

Our investigation traced this back to a backend service job that was causing the errors. As a remediation step, we manually ended the job which reduced the rate of errors back to normal and resolved the issue for all affected users.

3:57 PM PST

Users should no longer be experiencing any service degradation. Apologies for the trouble today and thank you for your patience.

10:14 AM PST

Some users may be experiencing general service degradation, some actions within Slack may fail and need to be retried.

We're on the case and are investigating. We'll share an update as soon as we know more.
