Challenge 2: islands

My team would like some clarification regarding the new section on islands in the problem formulation dated Sep 8 for Challenge 2. 

The document indicates that the problems will not have islands in the networks associated with the prior operating points for the base case and all contingencies. However, changing the line statuses may potentially result in the formation of islands. Will there be any penalties if our switching decisions result in the creation of islands?

Thanks!

The data assumptions guarantee that the power system as represented in the problem data is connected, but the problem solution is allowed to create islands. There is no penalty assessed to solvers for creating islands.
