Get a TLS cert from Github for the custom domain #66
Via isaacs/github#156, it has been possible to get issued a certificate for a custom domain for a few months now. I'm not entirely sure about the process, but maybe it's enough to just disable and re-enable the custom domain in the repository's preferences?
https://help.github.com/articles/troubleshooting-custom-domains/#https-errors might also have something about this.
Ah, thanks for the reminder!
@brakmic, you currently manage the rust.cologne domain and said in #43 that you wanted to do so for another year (November 2018). Do you want to transfer it to one of us? Also, can you change the A records of the domain to (one of the) IP addresses listed here to enable Github's HTTPS support?
