How does github pages find a web page?

description

Last year, when I changed my domain name, because github pages does not support binding multiple domain names,
, I used a method that I don"t know where to find a 404 page to jump to a new blog corresponding article.
now I don"t know where that 404 page is, and now I don"t know how to change the page.
I searched all branches of all my warehouses and couldn"t find where the file was.
search for keywords under each warehouse and cannot find

data that can be found now:

  1. Domain name resolution:

< del > here I can only see that I have directly CNAME to the new domain name and a Baidu statistics (added statistics on page 404), and I feel like I haven"t done anything else < / del >
< del > old domain name: lxy520.net (I don"t know why I configured it this way) < / del >
< del > Picture description < / del >
New blog domain name: ystyle.top

  1. blog

New blog address
New blog Warehouse address

Old address jump page (any 404 page is fine): lxy520.net/2016/04/16/docker-jenkins-git-mavenzi-dong-hua-gou-jian-yu-bu-shu
source code (chrome access): view-source: http://lxy520.net/2016/04/16/docker-jenkins-git-mavenzi-dong-hua-gou-jian-yu-bu-shu

3 question:
how can I find out where view-source: http://lxy520.net/2016/04/16/docker-jenkins-git-mavenzi-dong-hua-gou-jian-yu-bu-shu pages exist


I rummaged through it again and finally found the code in a branch of a fork repository (I don't know why the brain was so hidden at the time).
