Users may be having trouble loading Slack.

Issue summary:
On August 21, 2023 from 8:00 AM PDT to 8:51 AM PDT, less than 1% of users experienced trouble loading Slack.

We determined that a recent code change on our back end was resulting in a higher than expected memory footprint, and that this combined with high traffic loads was causing these issues.

We immediately rolled back this change, which resolved the issue for all affected users.
