If AWS goes down, no one will blame you for your web store being down as pretty much every other online service will be seeing major disruptions.
But when your super small provider goes down, it's now your problem and you better have some answers ready for your manager. And you'll still be affected by the AWS outage anyways as you probably rely on an API that runs on their cloud!
It's a "feature" right up there with planned obsolescence and garbage culture (the culture of throw-away).
The real problem is not having a fail-over provider. Modern software is so abstracted (tens, hundreds, even thousands of layers), and yet we still make the mistake of depending on one, two layers to make things "go".
When your one small provider goes down, no problem, switch over to your other provider. Then laugh at the people who are experiencing AWS downtime...

Let's not stroke our egos too much here, mkay?
