How SiteUptime Works


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.


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.


Our software tracks these failures and logs detailed reports of the uptime/downtime of your website each month. These reports are available to you to browse via an account control panel.
