Re: WTF?
"On top of this, all of them had terms in the SLA which measured the length of any one period of down time, as well as ones dealing with both average and per incident downtime on individual machines within the system."
On one customer I had, any breached SLA would trigger a counter, by which you HAD to get back the said SLA in order for a number of months or face an early contract termination with no penalty.
Clearly, ESA doesn't play in the same play field !
