Wednesday July 2, 2025

Starting at 11:55 AM PDT to 1:51 PM PDT on July 2, 2025, some users experienced issues uploading files, including images. Files and images that were uploaded prior to this issue were not affected.

This issue manifested as an error message for some users, while others experienced uploads that appeared to complete but were inaccessible.

We traced this back to a misconfiguration within our file handling service causing incorrect service permissions. We identified the problematic code change and reverted them, restoring functionality to all affected users.

4:49 PM PST

This issue is now resolved for all users.

• Current status and recent actions taken: We implemented a fix to a backend configuration that resolves the issue. Users are able to upload/download images and files in Slack as intended.
• Scope: Users across all regions may have experienced trouble uploading/downloading images and files in Slack.
• Previous impact to end users: Users may have observed delays when uploading/downloading images and files in Slack. For users who received errors during the incident, the uploads were unsuccessful. For users who did not receive an error after uploading their file but were unable to view it, those files are intact and available. All files uploaded before this issue are available.

Thank you for your patience as we worked to resolve this issue. We apologize for any disruptions to your day.

The fix we implemented showed some improvement with files, but we're noticing an uptick in errors that we're investigating.

• Current status and actions being taken: We're investigating the increase of errors and working on a forward fix. Some users may still experience additional trouble with file uploads or downloads.

We'll provide another update in 30 minutes until impact is resolved for all users.

1:33 PM PST

We’re observing improvements to images and file sending, and are monitoring our health metrics. Affected users may see successful images and file sends.

Current status and recent actions taken: We implemented a fix to a recent configuration update and are observing signs of recovery. 

We’ll be back with another update once the issue is fully resolved. We appreciate your patience.

12:47 PM PST

We’re still investigating potential causes for this issue, but we have determined that users may see that uploads are taking a long time and observe issues when viewing files that another user has sent.

Current status and actions being taken: We’re actively investigating potential causes.

Estimated time to resolution: No estimated time.

Scope: Users across all regions may be experiencing trouble sending images and files in Slack.

Current impact to end users: Some users are reporting trouble with sending images and files in Slack, the uploads may appear stuck or continuously loading. 

Known workarounds: No known workarounds.

We'll continue to provide updates every 30 minutes until the impact is resolved for all users.

12:28 PM PST

Some users are reporting trouble with sending images and files in Slack, the uploads may appear stuck or continuously loading. We'll be back with an update as soon as we know more.

12:07 PM PST

Starting July 1, 2025 at around 12:00 AM PDT until July 3, 2025 at around 1:40 PM PDT, some users were unable to utilize the search functionality in our API documentation website (https://api.slack.com), resulting in a 500 or similar error message.

The backend system responsible for the search functionality encountered a delay in service changes. This delay resulted in not serving search requests properly.

We adjusted the backend logic to account for these changes, resolving the issue for all affected users.

4:43 PM PST

We rolled out a fix that resolves the search issue on our API documentation pages for all users. 

We apologize for any disruptions to your day and appreciate your patience as we sorted this out.

2:58 PM PST

Our work to fully resolve the search functionality in our API documentation (at https://api.slack.com) is still ongoing. We'll be back with another update once we have news to share. We thank you for your patience in the meantime.

We've also adjusted the title of this incident to provide clarification.

10:20 AM PST

We’ve identified the cause of the issue and implemented a partial fix. Users signed into a Slack workspace should now be able to search the API documentation as expected. 
We’re continuing to work towards a full resolution, and users who are not currently signed in may still experience some issues. Restoring full functionality for all users remains our top priority. 

We apologize for the inconvenience and will report back as additional information becomes available

10:56 PM PST

Further investigation confirms that the search functionality errors are isolated to api.slack.com. General search across Slack continues to function as expected. 
Our team remains actively engaged and is exploring all possible solutions to resolve the issue as quickly as possible.

We’ll continue to provide significant updates as additional information becomes available.

10:09 PM PST

We’re currently investigating an issue affecting the search functionality on api.slack.com. Users may encounter server errors when performing searches or accessing certain resources. Please note that our teams are actively investigating and exploring multiple paths to resolution.

We’ll provide an update in 30 minutes or sooner if additional information becomes available.
