What timeframe is mentioned for predicting an imminent outage?

• A. 5-10 minutes before
• B. Several hours before
• C. 30-40 minutes before it happens
• D. Right when it happens

Answer: (C)

Predictive outages are most useful when they give you a practical lead time to act. A window of about 30 to 40 minutes before the outage allows you to diagnose the issue, confirm it isn’t a false alarm, and run through remediation steps before customers are affected. It’s long enough to run runbooks, failover or scale services, reroute traffic, and coordinate with the on-call team, but not so long that warnings become stale or are dismissed as false positives. If you’re alerted only a few minutes beforehand, there isn’t sufficient time to implement fixes or changes. If alerts come hours ahead, teams risk chasing unreliable signals and wasting resources. If you only learn right as it happens, there’s no opportunity to prevent impact at all. The 30–40 minute window strikes a practical balance between timeliness and actionability, making it the most effective lead time for proactive outage management.
