Hi all,
Bill said "Also, as you mention with The Planet incident, downtime in this case was due to an accident. "
Again this is where the use of the "nines" percentage gets unreliable. The US Missile defence System reportedly has a guaranteed uptime of 6 nines ( 99.9999% ) - including accidents. But at what cost? The relationship between the nines and $$$ is very exponential.
So it comes down to the old adage of "you get what you pay for". But as mentioned before, don't get too hung up on these percentages, as they don't really give a good indication of the reality of quality of service.
kind regards
Gary
