An organization meets their service level objective (SLO) of 99.999% (Digital Leader)
An organization meets their service level objective (SLO) of 99.999% (`five nines`).
How much downtime do their end users experience per year?
A) 5 minutes
B) 500 minutes
C) 5 hours
D) 5 days
Solution
Correct answer: A) 5 minutes.
To calculate the downtime per year for an SLO of 99.999% (five nines), we can use the following formula:
Downtime (in minutes) = Total minutes in a year * (1−SLO)
There are typically 525,600 minutes in a non-leap year (365 days).
So, for an SLO of 99.999%:
Downtime (in minutes) = 525,600 * (1−0.99999)
Downtime (in minutes) = 525,600 * 0.00001
Downtime (in minutes) = 5.256
Since downtime is typically rounded up to the nearest whole minute, the organization's end users would experience approximately 6 minutes of downtime per year.
