As this week indicated, perhaps tick and tock are not sufficiently far
apart to be a good redundancy choice from a geographical failover
point of view or common mode failure point of view.

As part of a set of 8 servers as you indicate later, perhaps ok, but I
fear for people who think "Ok, I want redundancy, so... Tick and
Tock."  Which, it turns out, was significant quantities.
