It differs depending on where you are. In 50 years living in Austria and Germany, I experienced one power outage that I remember, it took one hour. My internet is out for a day or two every year and more often for shorter times, sometimes just a minute - the problem with this is you never know how long it will be and whether setting up something else makes sense, or if it will be back anyway before you are done.
Anyway, as I wrote elsewhere recently:
Maybe instead of waving it away, Roon could have a help page explaining such options (that don’t involve telling people to just use a different digital product. Vinyl is one way )
