Xfinity OnDemand failing: V301 - Cardio Unavailable?

Weird. I just got the recent software update on my Roamio Basic, so I don't know if this is related or not.

When I try to launch the Xfinity OnDemand app, I get the following pop-up message:

"App Temporarily Unavailable

Cardio is currently unavailable. (V301)

Please try again in a few minutes.

Searching for the the V301 area on tivo.com (as the link fails), the blame is pointed to Comcast. I'm not convinced...

I don't know why...
