Between 3:00 AM PDT and 11:00 PM PDT on October 22, 2025, some Slack users experienced trouble with searching. Search results for these users were either missing or only returning partially.

A backend indexing job, which processes search results, experienced a backlog of errors. The errors required a large number of job retries, causing the partial results. We implemented a fix by optimizing the retry handling logic, resolving the issue for all affected users.

We identified the cause of the issue and implemented a fix that restored the search functionality for both public and private channels.

We are sorry for any inconvenience caused during this incident.

We've identified the cause and have implemented a fix that restored some search functionality. We're still working to resolve an underlying issue connected to older content (like older messages) not appearing in search results. We'll provide an update once that fix is applied. Thanks again for your patience in the meantime.

We're continuing the investigation into the issue that’s affecting Slack’s Search functionality. Users may still experience issues when searching for recent messages or files, or may see incorrect results when using keywords or searching within channels. We’ll share another update as more information becomes available. Thank you for your patience.

We're continuing to investigate an issue that has resurfaced which affects the Search functionality.
Some users may be unable to find recent content, see incomplete or unexpected results when using keywords, or experience errors while searching within channels. 

We’ve identified residual impact from a previous incident and are working to restore functionality.
We’ll share another update in 30 minutes or sooner as progress continues. Thank you for your patience while we work to resolve this issue.

We've noticed that the Slack Search functionality issue has resurfaced, and we're investigating. A subset of users is seeing Search indexing failures for messages, files, reactions, stars, and pins. This issue affects both private and public channels. We appreciate your patience while we work to resolve this issue.
