Will changing my GitHub username make websites hosted on GitHub Pages inaccessible?

Question

For example, will abc.github.io/verbose/ (abc being my current username) be changed to xyz.github.io/verbose/ when I change my username to xyz? Will it be automated through GitHub actions?

Answer 1

When you attempt to change your username on GitHub, they explicitly mention that no redirects for GitHub Pages will be set up. Therefore, all links pointing to oldname.github.io/verbose/ will no longer work. It is even possible for someone else to register an account (or organisation) using your old username and then host their website there.
