recently got an update. my provider updated their end connections. they had fiber for long range, but for last mile/to home, they used copper coax, which they now have upgraded to fiber. they also updated our router from 2.4 Ghz to 5 Ghz, and also changed our plan from 50Mbit to ~200Mbit. There also is a price increase, but it was not that big, so net it was a positive.

Do not have a backup internet, i do also have a cellular connection (though currently my data pack is exhausted), If my it (home wifi) goes down for a short term (less than a week, more like 2-3 days), then it is fine, inconvinience for sure, but i personally would be ok. but if it goes out for longer, then it is a big isssue.
