It's not really possible for a single ISP to get to the level of quality that has no hours at a time outages. For minutes per year outages level quality you need at least two ISPs independent from each other and not sharing infrastructure. Which means they won't even be available to consumers in the US and other countries, where internet access market is monopolized. I mean I can't imagine a law mandating ISPs to effectively split into two companies with each providing an independent link to the premises and all that. But when there is a competition a consumer at least has an option to just pay for multiple links to multiple ISPs.
