It’s a AWS issue. From the other Sirius thread
“Hey friends! This is a little outside of my normal role here at Sonos, but I wanted to jump in and let you know we’re seeing issues with both Alexa Voice Control and SiriusXM as a result of an ongoing outage at Amazon Web Services (AWS). We’ve got folks working to get status.sonos.com updated with this information now, but some of our internal tools are also partially affected, so it’s taking a bit of time.
Sorry for the trouble! On the bright side, Amazon is aware and working on the problem.”
