I have tried to found out, where does GitHub store the code and files I commit? After a lot of search I found only that it is stored in the Cloud. This is too broad for me. I don't have (or don't know) the method, how to found exact answer.
Where does GitHub store my code and other data I commit? What is the hosting of GitHub?
Main servers are in the US based on my observations. git pull from San Francisco based server is lightning fast while Australian servers are significantly noticeably slower. Possibly some additional regional hubs too.
They were at some point hosted with racksapace, no idea if still are or not. https://www.quora.com/How-many-physical-virtual-servers-does-GitHub-have
