What is Uptime?
Uptime is the amount of time that a server is available. This is normally measured in percentages. Many web hosts boast an uptime of 99.9%.
More About Uptime
A high uptime percentage generally indicates that a server is reliable. This means that your website will be available to users at all times.
Some web hosts have backup servers to help maintain uptime if a server does fail. Server clustering is another strategy that helps to improve uptime. A server cluster is a set of interconnected servers that work to improve performance and service availability. If one server fails, other servers within the cluster will take over the workload of the failed server.
Many web hosts advertise a 99% uptime guarantee with their hosting plans. This means that the chances of server failure are very slim.
