  • Speeds up load times of your web content, such as images or JavaScript files

What is a Content Delivery Network?

A content delivery network (CDN) is a network of servers located in multiple data centers around the world. The goal of a CDN is to improve the availability and performance of the web content to the end-users.

How does the 1&1 CDN work?

CDN caches, after the first load of the page, the static content of your website and distributes it over a network of 34 data centers around the world. Visitors to your website will get the data from the closest server to their location, enabling your site to load faster in every part of the world.

How is 1&1 CDN more secure?

1&1 CDN protects your website by analyzing your traffic and determining what is legitimate and what is malicious. It will automatically make your website safer from spammers, SQL Injection attacks, DDoS attacks, excessive bot crawling, etc.
