Edge Delivery Network
An Edge Delivery Network (often part of a CDN) is a distributed network of servers located geographically close to users. In localization, it serves translated content from the "edge" location nearest the visitor (e.g., serving the French site from a Paris server), drastically reducing load times and improving user experience.
Speed is a Ranking Factor
If your server is in New York but your user is in Tokyo, the site will be painfully slow due to network latency (200-300ms round-trip). Edge delivery fixes this by caching your content on servers worldwide. When a Tokyo user visits, they connect to a Tokyo edge server that delivers content in 10-20ms. For multilingual sites, this is critical: each language version can be cached on regional servers, ensuring fast load times globally. Modern platforms like Cloudflare, Fastly, and Vercel offer edge networks. MultiLipi uses edge delivery to serve translations in under 50ms worldwide.
