How Often Should You Check Website Uptime?
Your monitoring interval directly controls how quickly you can detect downtime. This guide explains how interval choices affect detection time, costs, and alert quality — and how to pick a schedule that matches your business risk.
Short answer
For most small businesses, 5‑minute checks are a solid baseline. If downtime is costly, use 1‑minute checks and multi‑check confirmation to avoid false alerts.
What “check interval†means
Frequency defines detection time
Check interval (or frequency) is the time between monitoring checks. Shorter intervals detect issues faster. Many providers default to 5‑minute checks, while 1‑minute checks are common for higher‑risk services.
Plan‑based intervals are common
Monitoring platforms typically offer different intervals by plan, such as 5‑minute on free tiers and 1‑minute on paid tiers.
The tradeoffs: speed vs cost vs noise
Faster detection
A 1‑minute interval can detect short outages that a 5‑minute interval might miss.
Higher request volume
Shorter intervals mean more checks per month, which can increase cost and data volume.
False positives
Short intervals can surface transient network issues. Multi‑check confirmation helps reduce alert noise.
How to choose your interval
- Define your acceptable detection time (RTO).
- Estimate downtime cost per hour.
- Use 5‑minute checks for low‑risk sites.
- Use 1‑minute checks for revenue‑critical sites.
- Enable multi‑check confirmation to reduce false alerts.
Practical recommendations
Brochure sites
5‑minute checks are usually fine. These sites care more about availability than sub‑minute detection.
Lead‑gen sites
Use 1‑minute checks during business hours if leads are time‑sensitive.
Ecommerce
Use 1‑minute checks with multi‑check confirmation. Short outages still cost real revenue.
APIs and apps
Use 1‑minute checks, plus endpoint checks for login, checkout, or key actions.

FAQ
Is 1‑minute monitoring overkill?
Not if downtime is expensive. It’s common for paid plans to offer 1‑minute intervals to catch short outages.
Can 5‑minute checks miss outages?
Yes. Short incidents can start and end between checks, which is why some providers recommend 1‑minute monitoring.
How do I reduce alert noise?
Use multi‑check confirmation and avoid alerting on a single failed check.
Does check type affect interval?
Yes. Some check types (like domain expiry) change slowly and can be monitored less frequently than HTTP uptime.
