Except if they aren't quite as independent as people thought

  Well that’s the default pattern anyway. When I worked in cloud there were always some services that needed cross-regional dependencies for some reason or other and this was always supposed to be called out as extra risk, and usually was. But as things change in a complex system, it’s possible for long-held assumptions about independence to change and cause subtle circular dependencies that are hard to break out of. Elsewhere in this thread I saw someone mentioning being migrated to auth that had global dependencies against their will, and I groaned knowingly. Sometimes management does not accept “this is delicate and we need to think carefully” in the midst of a mandate. I do not envy anyone working on this problem today.
