 In other words, a public repository's forks will remain public in their own separate repository network even after the upstream repository is made private. This allows the fork owners to continue to work and collaborate without interruption. If public forks were not moved into a separate network in this way, the owners of those forks would need to get the appropriate [access permissions](/get-started/learning-about-github/access-permissions-on-github) to pull changes from and submit pull requests to the (now private) upstream repository—even though they didn't need those permissions before.

If you decide to make the repository public in the future, it will not be possible to restore these stars and watchers, and this will affect its repository rankings.

 If a public repository has anonymous Git read access enabled and the repository is made private, all of the repository's forks will lose anonymous Git read access and return to the default disabled setting. If a forked repository is made public, repository administrators can re-enable anonymous Git read access.
