What is a CDN (Content Delivery Network)?

A CDN (Content Delivery Network) is a network of servers positioned in multiple locations worldwide that store copies of a website's content, so visitors are served from the server geographically closest to them — dramatically reducing load time.

Why a CDN Improves Speed

Without a CDN, every visitor's request travels all the way to one central server, wherever it's located. A CDN shortens that distance, which matters most for visitors far from the original hosting location.

Additional CDN Benefits

• Reduces load on the origin server during high-traffic spikes
• Improves resilience — if one server location has issues, others take over
• Often includes basic security protection against traffic floods
