Uptime refers to the percentage of time a server is operational and accessible to users. It is usually expressed as a percentage, such as 99.9% uptime.
Uptime is an important factor to consider when choosing a web hosting provider because it directly affects the availability of your website. A high uptime percentage means that your website will be accessible to visitors most of the time, while a low uptime percentage means that your website may experience frequent downtime.
Some web hosting providers offer uptime guarantees, which means that they guarantee a certain level of uptime for their servers. If the uptime falls below the guaranteed level, the hosting provider may offer compensation or other benefits to affected customers.
