It seems that some people spend a lot of time analyzing their own hairy navel and think that it must be the surely be center of the universe due to its resemblance to a black hole. If you just turn the darn computer off, then you can claim that the reaons for the loss of availability is the computer and not the fault of data storage. A MTTDL of 10^14 or 10^16 is much larger than any number of trailing 9s that people like to dream about.
