Also, our test server is syncing updates and extras every six hours.
Does anyone know if there's a way for the fedoraproject servers to push
updates rather than our polling?
There's not


Bummer.  I guess we get to work with what we've got then.  Is six hours
a good mirror timetable?


This brings up (again) the discussion of whether if would be worth adding sync-flag semantics to the way we mirror (like what debian has been doing for years). That would allow downstream mirrors to monitor for a specific file every hour or so, and when that file exists with an updated timestamp (or something) then we can be sure that the mirror has finished it's own sync. The downstream mirror can then (more) reliably perform it's own sync, sleep for some hours and start all over again. So while we're still polling for updates, the risk of ending with an inconsistent mirror is reduced.

If this was implemented on all mirrors, we could effectively and very simply decrease mirroring bandwidth, improve mirror reliability/quality, reduce the number of update problems due to incomplete mirroring etc etc.

By now it should not be a big surprise, that I think this could be a good idea. I'll just keep pointing out situations where this could make a positive difference. ;-)
