IIRC Comcast/Xfinity has a planned outage announcement on it’s homepage after you log in. They may even send an email to your Comcast address.
I am not positive because I only check those pages when making the outrageous payments.
Then again I must add our Comcast triple play hasn’t been bad. After we moved to an apartment a few years ago we found zero OTA TV because a huge hill blocks digital signals. Our only option was Comcast which we had dumped at our house.
Considering the apartment complex owners are reluctant to let anyone rewire the building Comcast hasn’t done a bad job after I complained of a few things.
We get most all of the HD channels plus quite a few regular ones. Sometimes but not often there is rfi interference, from our eleictric reclining couch and chair for example, but only on a few channels and it is temporary.
Phone has been wonderful, much better than our cell service.
Internet dl averages around 20-25 mbps with highs over 50 and lows around 12. Comcaast advertises 16 so I am satisfied.
Bill is around $130/month which I think is high but we have been using the service more than we did at our house and our grown kids have had ...and dumped...Verizon, Direct and Dish at higher cost.
I wish Comcast offered a few channels like RFD but OTOH we do get Pennsyvania Cable News Channel, PCNC, that broadcasts live the PA farm show and other statewide events including the legislature.
All in all we are content for the time with Comcast.
The internet is the only thing I use the cabled connection for these days.
