When these things happen it's always good to check SiriusXM Help (SXM_Help) on Twitter
I heard people complaining a bit on twitter and thought it was a fluke. Reason being is they will always say it's a Satellite issue or that the Sat went down. If that were the case the phones at TSS would ring off the hook and I'd know immediately. But this was something that was some sort of a software glitch that went on for Some but not all of the older Sirius Radios.
