Issue summary:
From 11:37 AM PST to 11:48 AM PST on January 24, 2024, we experienced an unexpected amount of API calls to our servers that occurred within a short window of time. The volume of API calls resulted in some users experiencing latency loading channels and general difficulties connecting to Slack. We investigated the impact with a broad lens and began to observe signs of recovery around 12:09 PM PST.

During this time, we cautiously observed our health metrics to ensure our servers were accurately recovering. As a result of our thorough monitoring, there was a delay before we could confirm the issue was fully resolved. Our teams have also put in measures to help reduce the likelihood of this occurring again in the future.
