Interesting story and some good detective work but the ending isn't satisfying.
I'm guessing this is Direct Connect out of the Equinix/Ashburn location, so they are probably working with a partner. There are probably a few black boxes in between their servers and AWS S3 edges. If this is affecting them I would expect to see a lot of people seeing the same thing.
I'm not really surprised an AWS support team shrugged it off but it seems like there are some more pieces to this.
