> A technical problem was the lack of true strong consistency for S3

What use case made this cause an issue for you guys? My go-to resolution here is just to use immutable files (sha256'd filenames typically), though that does entail storing separate keys for every related object

We host a lot of files and we do need permalinks to them. We also need updates to be visible immediately for everybody.

Have you ever tested S3's eventual consistency? Just curious.

There's no explicit SLA, but I've heard rumor that they start getting paged at ~4 hours staleness, though that might not be actually-true. I would think it's pretty quick in the average case.

That's fair. Anything you don't need to resolve as redirects/file serving through an app is a big win
