This doesn't seem very conducive to fun. What if, for example, recruitment centers shut down for no reason, even though the region is in good condition?
Well, you need to puzzle together everything said in this topic to get the whole picture:
- region stats DO affect the likelihood of shutdown
- some buildings can operate even with horrible region stats, some may shut down even with perfect region stats
- the number of buildings affects the chances of shutting down
- if you absolutely need 100% reliability, with enough buildings of the same type and good enough region stats, it can be done
