Issue Summary:

From 9:30 AM PST on November 28, 2023 to 12:30 AM PST on November 29, 2023, some users in Asia were experiencing issues with Slack loading. Most of the impacted users were in Japan and India.

We traced this back to an unexpected spike in a database load for which we quickly saw recovery.

We monitored the situation closely and as the load reduced without intervention, we did not take any mitigating actions.
