CDN (Content Delivery Network)

Distributed servers that cache and deliver content from locations near users.

CDNs reduce latency, handle traffic spikes and provide DDoS protection by serving cached content from edge nodes worldwide. CDN benefits include faster TTFB, improved Core Web Vitals and consistent performance for international audiences. Every Wix site is served via the integrated CDN with global edge presence and automatic HTTPS.
