Uptime in web hosting refers to the amount of time that a server hosting a website is operational and accessible to users. It is typically expressed as a percentage and represents the reliability of the hosting service. For example, a hosting provider that guarantees 99.9% uptime should be operational and accessible 99.9% of the time.

Uptime is crucial for websites because downtime can lead to loss of revenue, damage to reputation, and poor user experience. Therefore, it is essential to choose a reliable hosting provider that offers high uptime guarantees.
