The page you are referring to says that WIRED internet is free until Oct 24. It says nothing about when free wireless ends and the tech person I talked to assured me that is was not a test but rather the new internet system. He did not say that it would be free forever, but he did say that he knew of no plans to charge for it.
In fairness to BobNed, two hours ago that page on the DIS did specifically state that the wireless access would only be free until the 24th. It has since been amended to add the comments about wired access.
