Introduction

A content delivery network or content distribution network (CDN) is a system of computers containing copies of data, placed at various points in a network so as to maximize bandwidth for access to the data from clients throughout the network. A client accesses a copy of the data near to the client, as opposed to all clients accessing the same central server, thereby causing a bottleneck near that server.

Mirrors

The current list of available mirrors is available at http://mirrors.sugarlabs.org/

Goals

  • Reduce bandwidth at primary download server.
  • Improve quality of service for users.
  • Move content closer to users.

Setting up a Mirror

Setting up a mirror is very easy. All you need is a web server which is available via http, and (if possible) rsync.
