What is a Content Delivery Network?
A content delivery network (CDN) is a network of servers located in multiple data centres around the world. The goal of a CDN is to improve the availability and performance of web content to end-users.
How does 1&1 CDN work?
How is 1&1 CDN more secure?
1&1 CDN protects your website by analysing the traffic you receive and determining whether it is legitimate or malicious. It automatically makes your website safer from spammers, SQL injection attacks, DDoS attacks, excessive bot crawling, etc.
Now even better with new features
Mirage™ – perfect optimisation of images for faster loading times
Mirage™ personalises how images are displayed for each website visitor, adapting to the screen of their device. It automatically detects the device type, screen size and connection speed of a visitor, allowing it to provide the perfect image size and resolution, and significantly speed up loading times.
Railgun™ – up to 700% faster loading times
Railgun™ ensures that the connection between the 1&1 server and the CDN server is as fast as possible for dynamic content. Content that can’t be stored locally is examined for changes and then forwarded in compressed form. The result is up to 700% faster loading for personalised and constantly changing websites! Railgun™ is included alongside 1&1 CDN or 1&1 CDN Plus with 1&1 Unlimited Plus and 1&1 Unlimited Plus (4 GB) Web Hosting packages, as well as with 1&1 Managed Servers.
Easy setup with just one click
1&1 CDN is available in two versions: 1&1 CDN is included free with 1&1 Unlimited and 1&1 Unlimited Plus Web Hosting packages, and also with 1&1 Managed Servers. For even higher levels of security and faster loading times, we recommend upgrading to 1&1 CDN Plus. Both packages are valid for one domain and include unlimited traffic volume – the choice is yours! Activation is completed easily via the 1&1 Control Panel.
