Ho-Chunk Nation President Marlon Whiteeagle says safeguards have been added to prevent computer issues like the ones that forced gaming centers to close two weeks ago. The nation’s I-T team locked down the network immediately so workarounds could be found. The statement released Thursday says no one specific individual was targeted, but very little additional information is being released. Five of the nation’s six gaming centers were closed Thursday, August 26th, and reopened the following Monday, August 30th. The Madison location remained open, but it, too, had some computer issues.
