# CDN network & back-ups

A content delivery network, or content distribution network (CDN), is a geographically distributed network of proxy servers and their data centres. The goal is to provide high availability and performance by distributing the service spatially relative to end-users.

## CDN network

The published content is hosted in Frankfurt EU (AWS) and distributed worldwide with the help of a CDN (Cloudflare). This ensures that your publication can be accessed quickly all over the world. For example, a visitor from Australia downloads the publication content from a local server nearby.

Publications can be [secured](/en/article/securing-your-projects-i59hzu/) at any time with a password or excluded from a CDN network. This way any sensitive files within a publication remains on one server (location: Amsterdam) and can only be accessed with a password.

The maximum amount of data you can use depends on the type of license. With each license version, it's possible to upgrade the data traffic.

* The original (uploaded) data, is always saved on our hosting location (Europe).
* Temporary data is saved on multiple servers (CDN) across the world. 
* There is an option to publish without using the CDN. Content will be directly shown from the hosting location.

## Back-up

Content (uploaded data & generated published data within our Maglr platform) is backed up daily with a retention of 7 days. A complete back-up occurs once per week. Inside both editors, there is a separate back-up function available for users. When a user makes a mistake, the user is able to extract 20 older versions of his project.

## Extract data from old back-up

It is possible to create a back-up once per month with data that goes back to 6 months. In case Maglr needs to extract data from an older back-up, extra costs will be charged because this task can take a few hours to complete. Contact support@maglr.com when you need to extract data from your back-ups.
