Most large IT organizations provide Service Level Agreements (SLAs) with there end-users. I never hear of a IT organization that fails to meet that obligation so my question is why? Is the obligation so low that it can't be not met or is IT management that good that it is responsible for meeting it.
A 99.999 uptime percentage means that in a 30 day month of 43,200 minutes every server could be down for 43 minutes and still meet that obligation. Are IT organizations setting their obligation too low?
I know that the vendors talk about uptime percentages of 99.9999 or 99.99999 but I don't see those percentages in Service Level Agreements. What percentage does your IT organization use?
