People have been asking for IPv6 Support on GitHub since years (probably a decade by now)
... and someone even got so annoyed that they decided to setup a dedicated website for checking this: https://isgithubipv6.live/
The fact that almost the entire internet is controlled by those evil companies is really fucking sad. I remember the old days when people, you know, hosted their own shit and used manual load balancing to keep large sites up and working.
