FireHydrant integrates with Atlassian Statuspage and can automatically create an incident as part of your incident response process.
Add the "Create a Statuspage.io incident" step to your Runbook. On the Details tab, add a title for the step. On the Conditions & scheduling tab, create rules that dictate at what point during the incident response process the status page should be published.
When this Runbook step executes, Atlassian Statuspage is updated with your custom message.
