This would extend to a service like amazon actually, where survival of the service would be an extraordinary effort in case this problem lasted for a long time.
The way you imagined it, as 100% uptime, is incorrect.
We've seen this story play out in other industries and it never works out well for average people. It's been astounding for me to watch the pace of this centralizing and who is helping it along.
The tldr; point is that a single service provider should not have the amount of control Amazon does over the Internet. At least that's my take.
I know my opinion on this wildly differs from the HN crowd and SV "decision makers" these days - what is so curious to me is that this is a complete 180 from that same demographic even 10 years ago.
If you want other infrastructure companies or decentralized internet, you are free to do that yourself via voluntary means.
