'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.
