That seems like a reasonable list.  The other thing to keep in mind,
though, is that some things can be lower on the list for trying to
duplicate.  eg, if the colo is down, the fact that a lot of the
developer infrastructure is down is fairly acceptable I think.  

Now if the colo is down because a hole opened in the earth and the DC
has fallen to the center of the earth, then it's another question.  But
then we're talking substantial disaster recovery and not just avoiding
SPOF for our users during colo downtimes
