What is uptime?
Uptime is a measure of the time a computer system has been “up” and running. It came into use to describe the opposite of downtime, times when a system was non-operational. The uptime and reliability of computer and communications facilities is sometimes measured in “nines”. Five nines means 99.999% reliability, which translates to a total downtime of no longer than five minutes per year.
Uptime is the percentage of time that a web site is working. For example, cyberCatholics.com has an uptime average of 99.86%, this means that your site will be down for a total about 1 hour each month. We monitor uptime of customer websites of many web hosts and we display this data on the host’s details page. Some other hosts also offer “uptime guarantees” but this is not as valuable as it might appear.
