I could be wrong and have no internal knowledge of the infrastructure, but it seems like a pull rather than push operation. In other words, the individual mirrors are periodically pulling/re-sync'ing with some sort of master. To avoid slaughtering the master, I think the mirrors are typically configured to check/sync probably once, twice, maybe six times a day and might even be at various intervals. And different mirror admins have different load concerns and probably thoughts on proper frequency of polling. Oh, and let me add, I really hope the master is hidden from us running "yum update"..... The announcement emails seem to be hitting us when the update hits the master. I think I recall a thread a long time ago that complained about the emails being held up to give the mirrors time to get - but now we have the reverse - emails before the updates hit the mirrors. These days, I'm tending the read the emails as a warning: here is what I am going to get hit with within the next 24 hours or when I run an update. I only get nervous if an announcement doesn't get applied and 24 hours has gone by. Then I think something went wrong, like this last batch that started this thread.... --Rob
