Question

if a soc has a goal of 99.999% uptime, how many minutes of downtime a year would be considered within its goal? approximately 5 minutes per year. approximately 10 minutes per year. approximately 20 minutes per year. approximately 30 minutes per year.

Answer 1

In a year:

365 days

24 hours each day = 8760 hours in a year (365 * 24)

60 minutes in every hour = 525600 minutes in a year (8760 * 60)

Given 99.999% uptime, downtime = 0.001 % (100 - 99.999)

Downtime in a year = downtime in 525600 minutes

Downtime in a year = 525600 * 0.001% = 5.256 minutes (approx. 5 minutes)

So option 1 is correct i.e. approximately 5 minutes per year.
