Intermittent tv and internet

First. When these outages occur, are they being officially indicated here with any info about them ?;

Use a cell phone internet service, a public WiFi hotspot, or a neighbor's internet if you need to in order to check it.

Or you can use the Xfinity App: https://www.xfinity.com/apps 

Currently says advanced modem status unavailable, voice data modem online and all other devices status unavailable. Could be due to the recent refresh.  I was upgraded to x class last week.  Seems like a lot of freezing when watching tv, or total black out.  When I run a test the wifi is out as I have to toggle it off on my phone in order to access the xfinity app.  Then it says no outages, up and running good/strong wifi when I know that’s not the case. 

And it’s totally out now again 

Finally got a hold of someone at xfinity and they say my modem is grey and not communicating with xfinity.  Another team will try and resolve within two hours.
