Case Study: Slack strengthens incident response with Incident.io

Industry Interviews Colm Doyle, Incident Commander at Slack

Slack, the collaboration platform used by teams around the world, needed a reliable way to coordinate major incident response at scale. As incidents became more critical and the company expanded globally, Slack faced the challenge of keeping response fast, organized, and calm even when its own service was degraded. Incident.io is referenced in the case study as part of the broader incident management ecosystem developers ask about, alongside Slack’s internal incident command process.

Slack implemented a structured incident command approach built around Slack’s own tooling, follow-the-sun coverage, shadowing, severity-based rotations, and CAN reports to manage incidents efficiently. The process automates incident channel creation, stakeholder invites, Jira ticketing, and central incident announcements, helping the team respond quickly and consistently. With this system in place, Slack reports strong reliability at “high nines” uptime, 15-minute response SLAs, and improved resilience during hard-down events where fallback runbooks and off-Slack systems keep recovery moving.
