Interestingly, my country (Turkey) did ban github (along with google drive, microsoft onedrive etc.) back in 2016. However they reopened it within hours (18 hours to be exact), because systems all over the country were failing. One of the driving reasons was that ATMs stopped working. Appearently they were downloading some updates from github to function.

Stupidity has no limits.
