=Technical Notes=
Steam used to have a huge amount of servers (some from Limelight CDN) located around the world and older versions of the software used an inefficient method to connect users to the servers. Steam has made a big improvement on the's game delivery system by usinguses 3 different high performing CDN companies: Akamai, Highwinds and Level 3.
*media.steampowered.com = Akamai
*media3.steampowered.com = Level 3
*media4.steampowered.com = Akamai
Running steam will download a small file (containing a list of files with SHA-1 checksums and size in bytes to check if steam is up to date) from:
*client-download.steampowered.com
If steam is outdated, it will need to download the updated files by randomly selecting one of the CDN hosts and that host will be used to serve the files.
==Origin Server==
The origin server is where each CDN will pull the files from. The origin server hostnames are:
*cdn-01-origin.steampowered.com
==Steam Cloud==
The steam cloud normally stores saveda gamecopy dataof local saved games, allowing you to use that datathem on another system running the steam client. Here is a list of which hostnames belong to which game:
