Reduce global latency, pass Core Web Vitals, and serve static assets from edge locations — without breaking your site.
Over 53% of web traffic now comes from outside a site’s home country. Without a CDN, every visitor — whether in Tokyo or Toronto — must fetch assets from your single origin server. This causes:
