No idea. There should be ways to delay, or perhaps limit the failovers i some way. If you're having some network issues, it might be better to have users experience some delays on the primary than failing back and forth to a secondary.

It depends on your setup and the situation, but I've seen places where clustering is failing back and forth because of some network or other non-client issue, and this results in client downtime, and at times, someone just removing a node or two from the cluster so clients can work.
