Incidents are the primary method to inform your customers of a service downtime. When you have a downtime event, you can create an incident to describe the issue and its affected services.
As your event progress, you can continue to update the incident by creating an incident update. You can assign an incident status tag to each update to categorise what are you doing with it, i.e fixing, updating, investigating, monitoring.
The incident will be posted to your status page, allowing your customers to stay up-to-date with the downtime event that may have been affecting them.
