More like a third of a day.

  100 - 99.9 = 0.1 percent downtime.
0.1 is to 100 as x is to 365 (0.1/100 = x/365) becomes:
  x = 0.1 * 365 / 100 = .365 days down a year
  .365 * 24 hrs = ~ 8.7hrs down a year.  

Assuming the 99.9% figure is accurate.  
If they had said 99.99% that would be less than 1hr of downtime a year. 
In my opinion 99 anything is a marketing term.

What is it with this list and numbers ... :)
