# Uptime Monitoring ### What is the purpose of uptime monitoring? Our uptime monitoring is the core of our services. It will let you know when your website is fully non-operational. In terms of all of our monitoring, it is the most extreme and the most severe when alerted. It looks for any moment where your website does not load. This can be due to server issues, software issues or issues related to domain expiration, SSL certificate expiration, DNS changes, visual changes and significant changes in page speed. Therefore, unlike the other monitors, it is directly related to the success or failure of other areas UpWatch monitors. ### How does it function? We monitor your website using three different uptime monitoring tools. The package you choose determines how often the website is monitored. At the top level, your website is monitored every 30 seconds. The tools look at the website every 30 seconds and ask it to load. If it takes more than another 30 seconds to load or it returns an error message, they send out an alert. We use three different monitors simply because one is never enough! From experience, one tool can alert that there is downtime when the website is perfectly functional, or it can say nothing when the website is down. Monitoring across three tools ensures complete awareness when your website really is down, and it reduces the chance of us incorrectly worrying you. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
