2. Clusters will fail to fail over
3. Your plan does have a whole in it. None of us are perfect and if we make a plan it will have a flaw or exploit that we cannot see or manage in a cost effective way.
4. Whatever you planed for should be re-planned until you feel you’ve covered all your bases. (See Below)…
