I'm not sure the idea of putting the VPS on separate servers helps
improve uptime.  If the chance of a server going down is the same for
all servers, then sticking my web VPS on one physical machine and my
DB VPS on another physical machine would double the occurrences of
downtime in the case that my website is reliant on the DB (which is
99% true for Drupal sites - the 1% being boost or reverse-proxied
sites).  Right?

Or am I missing something?
