Technical Summary:

On February 21 between 7:00am PT to 9:20am PT, some users experienced connectivity issues with Slack.

The connectivity issue arose from a misconfiguration that was discovered by our engineers. At 8:45am PT a change in the configuration led to users being able to successfully connect to Slack again.

We’re hard at work on scoping preventative measures to ensure this doesn’t happen again in the future.
