San Francisco - KTVU and KICU digital subchannels all unavailable

I first noticed this on Catchy Comedy, but looking at all of the digital subchannels associated with KTVU and KICU all of them have the same multicolor vertical bar pattern and high pitched tone.  Some channels say "Sutro DR Master Control" while others have the station call letters and number and then DR Master Control. 

When I first noticed the issue earlier this week on Catchy Comedy, nothing displayed on the channel at all.

I see that someone else started a thread with the same problem for the Movies! subchannel (a KTVU channel), but apart from some people saying that they spent a long time on the phone with Xfinity reps there have been no answers or solutions.

Does anyone have an updated status on this issue?  I loathe the idea of actually trying to call because it seems to be impossible to reach anyone at Xfinity now anyway unless you speak into the automated voice recognition system that you want to cancel your service.
