Trouble with SCIM deactivating users

Issue summary:
From April 19, 2022 at 4:38 PM PDT to April 20, 2022 at 12:36 PM PDT, our SCIM endpoint began deactivating some users.

This was the result of a code change in a recent patch to fix a bug affecting the way SCIM handled user profile updates.

We reverted this code change to prevent new deactivations. We then restored affected user accounts, group memberships, and integrations to their prior states.

Note: Since initially posting, we've edited the times included in this summary to accurately reflect the duration of the issue.

Note: We discovered a small percentage of users who were still deactivated until April 21, 2022 at 10:40 PM PDT, and we have restored their accounts.

Trouble with Certain Features on Enterprise Grid

Issue summary:
On April 19, 2022 from approximately 1:00 PM PDT to 3:50 PM PDT, some Enterprise customers may have experienced delays related to reminders, notifications and other task-related features.

These issues were caused when the Primary Owner’s email address of a large load-test org was updated, which resulted in the delayed processing of Enterprise job queues. After identifying the issue, we released a fix to resolve job queue delays and return Enterprise job processing to normal.

Note: timestamps in this summary were edited after posting to reflect the accurate duration of this issue.

7:48 PM PST

We've traced the performance issues back to a job that had backed up the queue responsible for handling actions taken by users and administrators in Enterprise Grid organizations.

The backlog of tasks have completed and all features should be working as expected, though we recommend reloading the Slack app (Cmd/Ctrl + Shift + R) just in case. Thank you for your patience.

4:53 PM PST

Enterprise Grid customers may be experiencing trouble using certain features in Slack. This may include setting custom statuses and creating channels, and we’ll continue to provide updates as we learn more.
