Since Scott isn't posting any news updates (that I've seen) about the Dish vs CBS dispute, I can confirm that the Chicago CBS affiliate just got dropped.
The screen message says: "Sorry for the interruption of service. There is no need to call us. We are aware that this TV station is temporarily unavailable and will have this channel back as quickly as possible."
