The best way I've heard it described is "complex systems run in degraded mode".

Basically once a system is complex enough some part if it is always broken. The software must be designed from the assumption that the system is never running flawlessly.

No doubt but that's pretty high overhead for many projects colo is actually a decent choice but I guess that's not a popular opinion.
