Update: Missy with Skybeam Customer Care sent me an email for me to reset my unit. I did, and it's working again. She did tell me that I will be getting a credit for the days I was out of service.
You're welcome! In fact when the tech showed up at my house on 5/6 he input IP and DSN addresses for Skybeam and my system was up and functioning again. I have contended all along that someone turned off the Partnership Broadband addresses without telling customers what the new addresses were.
