'DR' is an obsolete 40-year-old mainframe concept; it never works, as  
funding/testing/scaling of the 'backup' systems is never adequate and/ 
or allowed.

Layer-2 between sites is evil, as well.

Layer-3-independence and active/active/etc. is where it's at in terms  
of high availability in the 21st Century.  GSLB, et. al.
