What Is Uptime?
Uptime is the proportion of time your website or application is up and available to visitors. It is usually quoted as a percentage, such as 99.9%.
It matters because every minute of downtime can mean lost sales, missed enquiries and damaged trust. High uptime is a core measure of how reliable your hosting and service are.
An Everyday Analogy
Uptime is like a shop's opening hours. If the doors are locked when customers arrive, you lose business — so you want to be reliably open whenever people come knocking.
- Measured as a percentage of time live.
