It's not setup that way now, because we use it to check the health of our own hiveminds, and we keep them at least functionally similar at all times (although we run different codes on them simultaneously sometimes, to see how they behave differently, especially when testing optimizations).
There are more advanced things that could be done though, such as having a haxproxy that is distributing its load do cross-checking on the responses from different nodes to API calls that should have the same answers from each node. But I think that's overkill for now.
