About this tool
Chaos Engineering Blast Radius Estimator
The Chaos Engineering Blast Radius Estimator computes affected users and downstream service impact from experiment traffic percentage and dependency count, with abort condition recommendations.
• Estimate blast radius before running a Chaos Monkey experiment in staging
• Calculate downstream impact before injecting latency into a shared service
• Determine whether circuit breakers are sufficient to contain a planned chaos experiment
• Size the blast radius for a gameday exercise proposal

FAQ
What does this tool tell you?
The Chaos Engineering Blast Radius Estimator computes affected users and downstream service impact from experiment traffic percentage and dependency count, with abort condition recommendations.
What affects the result most?
Blast radius = percentage of traffic or users affected if the experiment fails to stop correctly. Dependency fan-out: one service failure × downstream dependency count = blast radius multiplier. Circuit breaker protection: if circuit breaker is open, dependency failure is contained.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
