Downtime – how much does each 9 matter

This question was asked of me today so I felt that I would properly report what the downtime reports translate to when 9’s are trailing the decimal in a SLA.

 

Availability Associated Downtime per Year
99% 87 hours and 36 minutes
99.5% 43 hours and 48 minutes
99.95% 4 hours and 23 minutes
99.99% 53 minutes
99.999% 5 minutes
