Most all channels are missing from channel lineup

Perhaps this is not related, but my channel guide, set to Free to Me, suddenly stopped showing most of my channels and I had to switch back to All Channels.
I’m now finding no availability to most of my channels on any device. Bill paid, not late. I have most channels normally. Logged out and back in. Apps on iPhone and iPad also only allows for a handful of channels. My account shows things correctly.
“Subscription Needed” message....

We are having the same issue! We are paying for the 140+ package. We can view the channels from the tv box but not record. If you try to stream online it says it "requires a subscription". Also when I go to the list of my tv lineup it has changed to just the basic lineup. I tried calling support this morning and he couldn't figure out the issue. Xfinity must have done an "upgrade" on their end that is causing problems.

Same here. I should have 140 channels ii have what appear to be Basic. Support can't help so far...

The @ComcastCares twitter team replied with this earlier today (Saturday):

"...At this time it is showing this is a know issue. Are technicians are working to get this resolved asap and at this time the ETA is 5pm est. This time is estimated and can be resolved sooner or later."

Never heard of @ComcastCares and didn't see a response here, where I and others posted. I will use that in the future. Thanks for the heads up.

I really don't care for this site as it's clunky and difficult to navigate, just my opinion. But I don't know where else to go to ask questions. 

After hours on the phone and escalation within Comcast support, they told me that they are having a back end outage.  They don't tell their lower tier support people, and you can't find it online, and they couldn't tell me when it would resolve.  It's been 24 hours now for me.
