We are no longer seeing Slack API errors and have no reason to believe this will reoccur.
As a reminder, whenever Slack has an issue like this our web dashboard, mobile app, and all other incident.io services will continue to work. So if there is ever a Slack issue, jump into the web dashboard to run incident response actions from there, if needed.
We'll be reaching out to Slack to understand what happened.
Thank you for your patience.
