There's a page on g.o somewhere that explains this. I read it a long time ago, not sure how much has changed. I think it updates like every 30 minutes or something but I seem to recall that some servers can adjust that to hours or even just once a day if they need to. It's been a while but I bet it is still over there somewhere. Got curious so I went and found it. https://wiki.gentoo.org/wiki/Project:Infrastructure/Rsync There are two links there. Top one should give you a general idea. Dale :-) :-)
