Issue summary:
On July 4, 2022 from 12:31 AM PDT to 5:25 AM PDT, some customers experienced issues sending messages in Slack. We investigated and found that it was linked to a temporary issue with the memory requests. To resolve the issue, we downsized the memory management units, which restored functionality for all affected users. We identified the root cause to avoid this happening again.
