Issue summary:
On January 24, 2023, from 5:50 AM to 9:30 AM PST, some customers experienced errors when opening threads and saw blank channels and direct message histories.

We traced this issue to an unexpected spike in a database load. We made a configuration change that restored full functionality to threads and conversations for all impacted users.

We are investigating ways to prevent this from occurring in the future.

You may need to reload Slack (Command/Ctrl + Shift + R) in order for the fix to be reflected on your end. We're sorry for the disruption we brought to your day.
