Microsoft The outage on Microsoft's Windows Azure cloud computing platform that caused the government's G-Cloud service to go offline was the result of a calculation error caused by the extra day in February due to the leap year. Writing on the Azure blog the firm's corporate vice president for service and cloud, Bill Laing, said while the firm had still to fully determine the cause of the issue, the extra date in the month appeared the most likely cause.

"And on top of that 1 day in 366 is probably well within agreed outage levels (I'd guess they have 99.9%, so they would be covered.)"

Let me show you some magic:
100-1/366*100 => 99.73%
99.73>=99.9 => false

By Jove! Please, civilized man, teach me your mathmagics!

I guess, what I'm trying to say is: what were you thinking when you decided to snark instead of simply correcting my mistake?

let me show you some marketingmath:
100-(1/(365+365+365+366))*100 = 99,93
99.93 > 99.9, so no problem for the uptime guarantee ;)

(and even if the SLA were for 99.99 and this month will only be 96.55 that probably only means you will get a refund of 99.99-96.55=3.44% of what you pay per month)
