Whenever
I am confused & bored of my work ....i take some time to write about
IT, Services, Quality, Methodologies ....etc in my blog…before that ..the only
thing that strikes in mind to visit Stephen Mann Blog ...after reading his blog
...i just forget to write and blindly share the content written by Stephen...I
hate that...but Stephen always writes in practical way and that’s what I like
& admire ...as i am working in Telecom IT Service Provider
company...always had this confusion about defining/calculating application
availability.
Availability
SLA target in most of the case defined as 99.999% or 99.955%.....
How
do we calculate the availability??
Is
it possible to meet the defined target of 99.999% ??
The
way which we calculate the Availability SLA is correct ??
Do
we consider Planned Downtime while deriving availability SLA's??
Do
we consider nodes/regions?? Users impacted??...

Rance has answered my most of queries and Stephen has posted this article in
his blog......interesting & worth reading....
