Complete Guide to Website Uptime Monitoring

What is website uptime?

Uptime is the amount of time your website or service is available and functioning as expected. It's typically expressed as a percentage over a given period.

Why uptime monitoring matters

Uptime directly affects revenue, customer trust, and brand reputation. Without monitoring, you may not know about issues until users complain—or churn.

Core components of an uptime setup

A basic uptime monitoring setup usually includes:

• Checks that run on a schedule from one or more regions.
• Alerting to notify you when checks fail.
• Dashboards and reports to understand history and trends.
• Status pages to communicate with customers.

How to set up uptime monitoring

Start by listing your most critical services—homepages, APIs, and user flows. Set up monitors for each and configure sensible alert thresholds so your team gets notified quickly without being overwhelmed.

Common pitfalls and best practices

Avoid over-alerting on minor issues or running too few checks to catch real incidents. Review your monitoring setup after each incident and adjust thresholds and intervals as needed.
