Uptime is a measure of the time a computer or service is working and available.
The opposite, downtime, is the time when it is not available. Uptime is used to measure the reliability and stability of systems and services.
There are lots of different ways to measure uptime, so you need to figure out what measurement makes the most sense to you.
Uptime is measured in percent,
with the ultimate goal of reaching 100%.
However, since most systems don't reach 100%, uptime is often expressed as a number of "nines". For example, "five nines" would mean 99.999% uptime.
That very much depends on the type and size of
business you're in. Estimates for one hour of downtime
are in the $180,000-$300,000 range per hour.
