Q: How do I pick the right check interval instead of just maxing it out?

Q: How do I pick the right check interval instead of just maxing it out?

A: Tighter isn't always better. Match interval to what the page costs you when it's down.

— Revenue/checkout pages: 30-60 seconds. Every minute down is money.
— Marketing and blog pages: 3-5 minutes is plenty.
— Internal tools and staging: 5-15 minutes.
— APIs that feed live features: 30 seconds with a body-content check.

Now the math part: at a 5-minute interval your worst-case detection delay is ~5 minutes before the first failed check even registers. Add your confirmation checks on top. If your SLA promises detection inside 2 minutes, a 5-minute interval can't deliver it.

Follow-up: 30-second checks across 50 endpoints can rate-limit your own API. Stagger them.
