Uptime

99.99 uptime

the period of time when a computer, system, etc. is being used without any problems.

What that means in real time:

UptimeTotal downtime per year
99.00000%3 days, 15 hours and 39 minutes
99.90000%8 hours, 45 minutes and 56 seconds
99.99000%52 minutes and 35 seconds
99.99900%5 minutes and 15 seconds
99.99990%31 seconds
99.99999%3 seconds

So this is downtime per year! (source: Matt Rickard - @mattrickard at Twitter)

At Fuga you get a 99.99% uptime SLA,

although we are actually between 99.99% and 99.999%. But let’s assume 2x9 behind the dot:

52 minutes and 35 seconds per year

s 3155 seconds per year

Divide by 365 days makes (rounded up) 8.64383 seconds per day

x7 = 60.50681 seconds per week

That’s an itsy bitsy teenie weenie more than 1 minute of downtime per week!

For every extra 9 after the dot you should take into account a multiplication of 10 for the costs. If you know what it will cost you to be down for 1 minute, you can make an offset against the costs you will incur for wanting that extra 9 behind the dot in your SLA. Because everything is possible, we know that, but these kinds of considerations deserve a fair calculation.
