What is an error budget?
An error budget is the total amount of unreliability your SLO permits — 100% minus your SLO target, applied over your chosen period. It's the same math as an SLA downtime allowance, but framed as a budget SRE teams can spend on releases, experiments, and planned risk instead of just tolerating outages.
Frequently asked questions
What's the difference between an SLO and an SLA?
An SLO is your internal target, usually stricter than the external SLA you've contractually promised — see the Guides page for a fuller breakdown.
Should my SLO equal my SLA?
Generally no — set the SLO tighter than the SLA so you have warning room to react before you actually breach the external commitment.
