Something is wrong before everyone corrects their behavior. When mistakes happen, some people learn immediately and change their habits, while others do not. But gradually, over time, there are fewer central points of failure and the whole thing becomes more resilient. A similar situation may arise here. If any of these primary nodes fail, people are more likely to use smaller nodes in the future. All I can suggest is to keep a close eye on it, see what develops, then make a backup plan if it seems to get worse.
