Uptime is a measure of the time a service has been "up" and operational. It came into use to describe the opposite of Downtime (time when a service isn't operational). Availability refers to the ability for a user to access and utilize a service. The uptime and availability of a service is sometimes measured in "Nines," the critical metrics of reliability. "Six Nines" means 99.9999% availability, which translates to a total downtime of approximately 31.536 seconds per year. The other "Nines" are "Five Nines" 99.999%, "Four Nines" 99.99%, "Three Nines" 99.9% and "Two Nines" 99%. To learn more, please visit our Uptime & Provider Info page. [less]
