Incident Response

Why Incident Response Matters

Production systems fail. Databases run out of connections. Third-party APIs go down. Deployments introduce bugs. Traffic spikes overwhelm capacity. The question isn’t whether your application will have an incident. It’s whether your team will handle it in minutes or hours.

Without incident response procedures, every outage is a crisis. Engineers scramble to figure out what’s wrong, who should fix it, and how to communicate with customers. They check the wrong things first. They make changes that make the problem worse. They forget to communicate status updates. What could be a 15-minute recovery becomes a 2-hour outage with a side of customer churn.

AI-generated applications are especially vulnerable. The code works in the happy path, but error handling is surface-level. There are no runbooks because nobody thought about failure modes. There’s no monitoring to tell you what’s wrong. The first time production breaks, the team discovers they have no tools, no procedures, and no practice dealing with incidents.

What We Build

Runbooks:

• Step-by-step procedures for known failure scenarios
• Decision trees for diagnosing common symptoms (high latency, error spikes, resource exhaustion)
• Service dependency maps showing what affects what
• Recovery procedures with exact commands and expected outcomes
• Rollback instructions for every deployment type

On-Call Systems:

• PagerDuty or Opsgenie configuration with proper escalation paths
• Alert routing based on service ownership
• On-call rotation schedules that don’t burn people out
• Escalation policies that wake the right person, not everyone
• Alert deduplication so one incident doesn’t send fifty pages

Incident Management:

• Severity classification (SEV1 through SEV4) with clear definitions
• Communication templates for status pages and customer updates
• Incident commander roles and responsibilities
• War room procedures for major incidents
• Real-time status page integration (Statuspage, Instatus, or custom)

Postmortem Process:

• Blameless postmortem templates
• Timeline reconstruction from logs and metrics
• Root cause analysis methodology (5 Whys, fault trees)
• Action item tracking with ownership and deadlines
• Review process to ensure action items actually get done

Incident Prevention:

• Chaos engineering practices (game days, failure injection)
• Pre-deploy checklists for high-risk changes
• Change management procedures that reduce deployment risk
• Capacity planning based on growth trends

Our Experience Level

We’ve been on-call for production systems since before it was fashionable to call it SRE. We’ve managed incidents ranging from simple deployment rollbacks to multi-hour outages affecting thousands of users.

We’ve built incident response programs from scratch for startups that had no process. We’ve improved existing programs for teams that had procedures but didn’t follow them. We’ve run game days that revealed gaps nobody expected and postmortems that prevented repeat incidents.

We’ve configured PagerDuty and Opsgenie for teams of all sizes. We’ve written runbooks that actually get used during incidents because they’re findable, readable, and accurate. We’ve established postmortem cultures where engineers share failures openly instead of hiding them.

When to Use It (And When Not To)

If you have users who depend on your application being available, you need incident response - even if it’s just a simple runbook and a monitoring alert that texts you when the site goes down.

For early-stage products with a small team, start simple. A runbook for common failures. A Slack channel for incidents. A postmortem document after significant outages. The process should match your team size.

For products with SLAs or paying customers, invest more. Formal on-call rotations. Severity classifications. Status page communication. Customers who pay you expect transparency and professional handling when things go wrong.

For larger organizations, incident response becomes a discipline. Incident commanders. Communication leads. Practice drills. Metrics on mean time to detection and recovery. Compliance requirements may mandate specific incident handling procedures.

Common Challenges and How We Solve Them

No runbooks, so every incident starts from scratch. Engineers waste time figuring out basic diagnostic steps. We write runbooks for the top ten most likely failure scenarios. Each includes symptoms, diagnostic steps, resolution procedures, and escalation criteria.

Alert fatigue that makes pages meaningless. Everything alerts, so nothing is urgent. Engineers ignore pages because most don’t require action. We ruthlessly eliminate noisy alerts, tune thresholds to meaningful levels, and ensure every page requires human action.

Postmortems that blame individuals. Engineers hide incidents because they fear punishment. We establish blameless postmortem culture. The question is “what in our systems allowed this to happen?” not “whose fault is this?” Psychological safety improves incident reporting and resolution.

No on-call rotation, so one person handles everything. A single engineer carries the pager and burns out. We set up proper rotations with backup escalation. We compensate on-call fairly. We reduce on-call burden by fixing the alerts that page most often.

Incidents that repeat because action items never get done. The postmortem identifies improvements, but nobody follows through. We track action items with owners and deadlines. We review completion in team meetings. We prioritize action items alongside feature work because preventing the next incident is a feature.
