lol I think the only reason you're being downvoted is because the common belief at HN is, "of course marketing is lying and/or doesn't know what they're talking about."
I didn’t downvote but s3 does have low latency offerings (express). Which has reasonable latency compared to EFS iirc. I’d be shocked if it was as popular as the other higher latency s3 tiers though.
I agree - we generally do the opposite of trusting marketing, but sometimes marketing is coincidentally correct.
Cloudflare wants to "protect" the world from the evils of DNS services other than themselves even knowing what geographical region people are in, so they strip all geographical information, even general, broad location, from DNS lookups. This has the effect of increasing latency for non-Cloudflare CDNs sometimes, since data will sometimes end up being served out of the wrong region.
I've wondered since I first heard about this if this is their way to enshittify CDN deliverability in general and make their latency look better in comparison.
