How SiteUptime Works

Monitoring

Multiple monitoring servers around the world run protocol based tests on your website at specific intervals (every 2, 5, 15, 30 or 60 minutes) 24 hours per day, 7 days per week, 365 days per year to ensure that your customers and users can reach your website.

Alerting

If more than one monitoring location detects a connection failure or error, an email or SMS alert is sent to you. Our system will also notify you when you website becomes available again.

Reports
