As per a previous comment, the contents of the pages linked have as much to do with Atlassian as the contents of a page on github.io have to do with Github.

This is a stanford.edu project wiki page, hosted by Atlassian. Nothing more.

By the same logic, any performance improvement that Github might see from random projects hosted on Github, should be "dogfooded" in the same way.

It's not dogfooding when it's someone else's work.

You aren't getting this.

Let's break this apart a bit more slowly.

They did not blog about this.

Their users did.

Atlassian, the company hosting it, did not write the post.

Their customers, the people using Atlassian's servers, did write the post.

Atlassian is not blogging about it. Someone else created a Confluence wiki site for RAMCloud using the shared *.atlassian.net domain. Anyone can create a site with a subdomain there.
