Worth noting that Netlify’s On-demand Builders provide global persistence across all edge nodes: https://www.netlify.com/blog/2021/10/25/faster-more-reliable-page-loads-with-update-to-on-demand-builders/
Alternatively, CloudFront has 13 Regional Edge Caches that (in my tests with a VPN) seem to be segmented too: https://aws.amazon.com/cloudfront/features/?whats-new-cloudfront.sort-by=item.additionalFields.postDateTime&whats-new-cloudfront.sort-order=desc
CloudFront also offers an Origin Shield product that appears to provide a similar feature but I have not enabled it: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cache-hit-ratio.html#cache-hit-ratio-use-origin-shield
