    '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.

    Sorry, sometimes I mistake your existential crises for technical
    insights.
