Are you fine with using the mac.r-project.org server as a default mirror on macOS? E.g. in RStudio, on GitHub Actions, etc? That's a lot of traffic.
mac.r-project.org is also not ideally located (i.e. much slower) for most users, especially compared to the CDN at cloud.r-project.org. Do you think it would be possible to keep the old binary packages around for a day or so? That would not only help with the sync issue, but also with potentially outdated metadata. AFAIR this is what Debian/Ubuntu repositories do.
