Issue Summary:

On Oct 4, 2023 from 11:15 PM PDT to around 11:58 PM PDT a small subset of users experienced trouble connecting to Slack and sending and receiving messages.

A code change optimizing resource usage caused a core service to restart causing brief connectivity issues for a few users.

The service recovered automatically and we’ve put measures in place to prevent this from happening in the future.
