Availability is measured in so-called nines notation, that corresponds to the percentage of time that a service is available. For example, if a service is available 99.9% of the time, we can say that has “three-nines availability”. This notation is used to gives us the specific amount of downtime that a service is allowed to have.  Next are the availability and downtime calculations for 99% availability to 99.999% availability : 99% availability (two-nines):         * 3.65 days/year (of allowed downtime)         * 7.20 hours/month         * 1.68 hours/week         * 14.4 minutes/day 99.9% availability (three-nines):         * 8.76 hours/year         * 43.8 minutes/month         * 10.1 minutes/week         * 1.44 minutes/day 99.99% availability (four-nines):          * 52.56 minutes/year        * 4.38 minutes/month        * 1.01 minutes/week        * 8.66 seconds/day 99.999% availability (five-nines):        * 5.26 minutes/year        * 25.9 seconds/month        * 6.05 seconds/week        * 864.3 mimiseconds/day
