Trouble with search

Technical Summary:
At 6:19pmPT on August 22, 2018 a change was deployed that caused Search to fail for all customers when they reloaded Slack on desktop or in a browser. This change was part of a larger effort we are taking to modernize and improve Slack performance.

The regression was identified at 6:35pmPT and reverting the change restored search functionality for all customers by 8:29pmPT. We have planned to add additional logging and testing activities to prevent this from happening in the future.

3:58 PM PST

We've deployed a fix to resolve the search issues. If you're still seeing failures, please reload Slack with Cmd/Ctrl + R, or reach out to us at Thank you for your patience, we're very grateful.

8:29 PM PST

We are still investigating the search trouble and working to determine the underlying issue.

8:14 PM PST

Searches in Slack may be failing for some users. We are all on hands on deck and looking in to this. We apologize for the trouble.
