Earlier this year I raised the topic on RediStack and Repository Mirroring to gauge public opinion on how/where to host and mirror the code repo.
GitLab should redirect all requests in perpetuity just fine as long as I don't reuse the
RediStack project name for a personal project.
Concerning mirroring to GitHub: I will continue to mirror the code to my personal GitHub project for the foreseeable future.
I will continue to post updates regarding any potential changes to the GitHub mirror, but will not be making any changes until at least March 2023.
