<div dir="ltr">Hey Daniel,<div><br></div><div>Around June / July this year valve migrated off of their old distribution system based around proprietary 'steam cache' servers to what they call "SteamPipe" which is a HTTP based CDN. When I last checked in early august only 10% or less traffic continued over the old steamcache system.</div>
<div><br></div><div>Steampipe itself is broken into 2 subsystems - Valves in house HTTP CDN and third party CDN's. The traffic split between these two systems is approximately 67% to 33% when i last looked. Valves in house system are all servers that fall below the subdomain of *.<a href="http://cs.steampowered.com">cs.steampowered.com</a> and australia currently hosts 3 of these servers - <a href="http://Valve217.cs.steampowered.com">Valve217.cs.steampowered.com</a>, <a href="http://Valve5.cs.steampowered.com">Valve5.cs.steampowered.com</a> and <a href="http://Valve6.cs.steampowered.com">Valve6.cs.steampowered.com</a>. The third party system is currently a mix of 6 vendors at last check using the naming system content*.<a href="http://steampowered.com">steampowered.com</a>. Each of these content 'servers' is mapped to a different global CDN and each one serves a different set of content - IIRC content1 servers authentication and store traffic, and content 3 and content7 serve game files. Content7 is the namespace for Akamai, Content1 is Limelight, 2 is Footprint, 3 is HighWinds, 4 is EdgeCast, and 5 is Amazon. 6 is now decommissioned and no longer in rotation.</div>
<div><br></div><div>In short, it is basically impossible for any consumer ISP to cache all of steam, the best they can do is host a bunch of the third party CDN's such as akamai and hope to get lucky and serve maybe 40% of steams traffic (although in my experience ISP's dont count akamai as freezone / unmetered)</div>

<div>Hi Guys</div>
<div><br>
</div>
<div>I was wondering if anybody on-list may know of any other Steam content providers other then the obvious IINET, Internode or Telstra based services run by those types of ISP's? and if they know the URL's?</div>
