How is server uptime calculated?
Uptime is calculated based on the number of hours that the system (server) is available during a given period of time and is expressed as a percentage. Let’s look at an example. We know that there are 365 days per year so in terms of hours there are a total of 365 x 24 =…
Uptime is calculated based on the number of hours that the system (server) is available during a given period of time and is expressed as a percentage. Let’s look at an example. We know that there are 365 days per year so in terms of hours there are a total of 365 x 24 = 8760 hours.Click to see full answer. In this way, how do you calculate uptime?We calculate uptime by calculating the minutes of uptime divided by the total number of minutes for the specified period. So, February has 29 days this year, 29 days x 24 hours x 60 minutes = 41760 minutes. 49 minutes of downtime, means that the site was up for 41711, and 41711 / 41760 = 0.9988, thus the 99.88% uptime.Subsequently, question is, what is uptime on a server? The Server Uptime is a time during which a server is operational. This time is sometimes measured in percentage. If the server uptime is 99.9% then it indicates the time for which the server is operational for 99.9% of the time. Additionally, how is server availability calculated? Typically, IT organizations use a percentage, such as 99.999% availability, to do this. Putting these numbers into the availability equation gives: Weekly availability = 100% x (168 – 8) / 168 = 95.2%. Monthly availability = 100% x (730 – 8) / 730 = 98.9% Quarterly availability = 100% x (2190 – 8) / 2190 = 99.6% How many hours is 99.99 uptime? Calculations: Uptime Percentage to Downtime Nines Downtime 99% Two Nines equals to 7 hours and 12 minutes downtime in 30 days 99.9% Three Nines equals to 43 minutes and 12 seconds downtime 99.99% Four Nines equals to 4 minutes 19 seconds downtime 99.999% Five Nines equals to 26 seconds downtime
