Internet broadcast radio stations disappeared from Apple Music

I listen to several broadcast radio stations via Music. Was listening to KUCI, CKUA, etc.

However now all such stations have disappeared from Music. Including say CKUA, which I was just listening to. On two Macs and an iPhone. I signed in and out of my account; no change.

CKUA doesn't show in recently played either. There is no recently played under "Radio" in the sidebar now. If I click any of the "More to Explore" categories of Radio, I get a blank page—nothing shows up no matter what category I choose. On the iPhone, it shows "An Error Occurred, Try Again." Not even that shows on macOS.

If I search I can find KUCI and KCRW, but not CKUA. But they don't show up any other way than searching.
