I would expect Dropbox, a file storage company that proudly invests heavily in tech and infrastructure to achieve a better availability than what they already were on AWS (99.99%)
In terms of availability the change is pretty much 0 and as a business / enterprise customer I might as well choose a different service with similar or higher 9s or (if my needs are complex) choose S3.

Here is a service that has managed to achieve 5x9s of availability:
Guaranteed availability is a bet they're willing to make, a gamble they've been on top of so far, a risk that, should something fail, they will pay out on according to their SLA.
I would have thought that given Dropbox's engineering talent, they would have designed a system that would account for 5x9s and even making that guarantee for enterprise or mission critical customers.
Can't even find their SLAs anywhere for these customers, so I presume that Dropbox doesn't care about them.
Guess I was wrong and this is just disappointing and made the move not worth it.
