Verify your failover actually works, before you need it to.

For teams whose resilience story rests on assumptions nobody has deliberately tested.

The problem

Why this keeps biting teams

Runbooks describe what's supposed to happen when a dependency fails. Whether it actually happens that way is usually untested, until a real failure reveals the retry logic was misconfigured or the alert never fired.

What we do
[01]
Identify the failure modes most likely to matter for your architecture and blast radius.
[02]
Run controlled chaos experiments in staging, then production, with a clear rollback plan.
[03]
Verify alerting, failover, and retries behave the way the runbook claims they do.
[04]
Fold findings back into the runbook and the architecture, not just a postmortem doc.
