Incident

Issues loading threads and activity feed

Issue summary:
On July 1, 2024 from 12:23 PM PDT to around 5:20 PM PDT, some users experienced issued with loading threads, channels, direct messages, the Activity tab, and search results. Some users may have also experienced issues with sending messages.

An error occurred during a routine database process. This error meant that a small subset of user requests were incorrectly routed to databases that did not exist.

We made an immediate change to redirect user requests to cached data where possible to mitigate some of the errors. In parallel, we rebuilt the database mapping to correctly reroute the affected traffic. This resolved the issue for all users.

9:17 PM PST

The issues with loading threads, activity, direct messages and searching items should now be resolved. We've seen significant improvements in error rates that are now down to normal/healthy levels. We're confident these items should now be working as expected for all users. Users may refresh Slack ⌘ R (Mac) or Ctrl R (Windows/Linux).

5:44 PM PST

We are still working hard to reduce errors to rectify the issues with loading threads and activity. Some users may still see issues with loading direct messages and search as well. We're currently working towards a resolution. We hope to see further improvements soon.
