As soon as a streaming service starts having availability issues, it will garner a reputation very quickly and lose customers just as quickly. Being able to serve N amount of content reliably and consistently (even if less than M amount) is still a strong demonstration of good engineering practice in my opinion.

On that point, I can't honestly recall a time I had Netflix streaming issues that weren't because of a problem on my side. Maybe I've just been lucky though, so ymmv.
