What Is Uptime and Why Is It Important?

Uptime measures the percentage of time your website is available and responding correctly. Most good hosting providers advertise 99.9 percent uptime or higher, but independent monitoring is the only way to verify this.

How Uptime Monitoring Works

Monitoring tools send regular requests to your website from different locations. If the site does not respond correctly, they log downtime and send alerts by email, SMS or messaging apps.

Key Metrics to Track

• Overall uptime percentage: The main reliability indicator.
• Average response time: Useful for spotting performance issues.
• Outage frequency: How often your site goes offline.

Practical Steps

• Set up monitoring for your main domain and key landing pages.
• Use at least two monitoring locations.
• Review uptime reports monthly to catch patterns early.
