Comment:
I had no particular time window in place.  I was largely going to handle this the same way as when repo.voidlinux.org was shut off where the domain was left on basically until I remembered almost a year later that it could be turned off.  I might be more aggressive with turning off alpha.us.repo.voidlinux.org though as that was never a default mirror and hasn't appeared in documentation for a long time.
