How does Cloudflare's Argo Smart Routing interact with S3 origin servers?

Argo Smart Routing analyzes real-time network conditions to route traffic through the fastest and most reliable paths to your S3 origin. While the origin remains your S3 bucket, Argo optimizes the connection between Cloudflare's edge servers and S3, potentially reducing latency and improving performance, especially for users geographically distant from your S3 bucket's region.
