Critical burn: roll back the last Vercel deploy and page on-call
When Honeycomb reports a critical fast-burn that started right after a deploy, this flow rolls back to the previous Vercel production deployment, opens a PagerDuty incident.

- OutputPost burn-to-rollback timeline in SlackSlack
What it does
Treats a critical burn that began just after a release as a likely bad deploy and reacts automatically. On a critical-tier Honeycomb burn-rate alert, it rolls Vercel production back to the prior known-good deployment, raises a PagerDuty incident for on-call, and drops a timeline into Slack tying the burn to the suspect deploy.
When to use it
Use it for high-stakes services where a fast-burning SLO right after a ship warrants an immediate automated rollback rather than waiting on a human. Requires a clear previous-good Vercel deployment and a PagerDuty service.
How it works
- 1Honeycomb sends a critical burn-rate alert webhook.
- 2A logic step confirms it is critical tier and correlates with a deploy in the last N minutes.
- 3Vercel rolls production back to the previous successful deployment.
- 4PagerDuty opens an incident with the SLO, burn rate, and rolled-back deploy id.
- 5Slack receives the full timeline: burn detected, deploy suspected, rollback done, on-call paged.
