What to do when an outage is not an "outage"?

I live in south-eastern Michigan and we had bad storms roll through last week.  Power was finally restored yesterday.  During this time, my xfinity Internet was out most of the time, but would occasionally pop back on for awhile, before going out again.  Yesterday, about an hour after power was restored, it stopped again.  I looked on the app (as I had done many times before) and it says there is no outage.  I work from home.  My Verizon hotspot data is gone, and I'm now being told that it's going to be Thursday before a tech can get to my house to check.  I'm essentially dead.

There HAS TO BE some kind of local outage related to the power incident that's not just affecting me.  Literally, everything was fine and then and then all of the sudden, it wasn't, and I changed absolutely nothing.  Even so, I disconnected all cables, reconnected, tried different cable outlets around my home, etc.  My modem still shows no connection (at all).  To be clear, this is not a wifi issue.  The modem itself shows no connection, and xfinity says it cannot reach my modem.

My concern is that my neighbors probably just assume this is still part of the "outage," but if xfinity doesn't believe there is an outage, then no one is going to be fixing it any time soon, and that's a serious problem for me, and I find it hard to believe it's just me that's having a problem, after everything else that has gone on the last few days.
