The Error Budget Policy Template, 2026 Edition

What happens when the error budget exhausts. The template that codifies the trade-off between feature velocity and reliability.

Trigger

Error budget exhausted (less than 0%): triggers automatic policy.

Approaching exhaustion (<25% remaining): triggers heightened review.

Feature freeze: only reliability work merges until budget recovers.

Increased on-call attention: review every change for risk.

Budget recovers naturally over time as the SLO window rolls. Or via reliability fixes that reduce future failures.

Track recovery; the policy should lift only when budget is materially restored.
