I think you&#x27;re referring to the GitHub Engineering blog post [1] about our git storage tier. We [2] store your code on <i>at least</i> 3 servers, which is an improvement in many ways from our previous storage architecture. There are a lot of servers [3] powering things but not the millions it would require to give every customer three dedicated machines. Developing efficient solutions to problems is a requirement (and a fun challenge!) for anything at GitHub&#x27;s scale.<p>[1] <a href="http:&#x2F;&#x2F;githubengineering.com&#x2F;introducing-dgit&#x2F;" rel="nofollow">http:&#x2F;&#x2F;githubengineering.com&#x2F;introducing-dgit&#x2F;</a><p>[2] I&#x27;m a GitHubber. <a href="https:&#x2F;&#x2F;github.com&#x2F;jssjr" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;jssjr</a><p>[3] <a href="https:&#x2F;&#x2F;twitter.com&#x2F;GitHubEng&#x2F;status&#x2F;730429227896463360" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;GitHubEng&#x2F;status&#x2F;730429227896463360</a>
