hi guy, 5.5 is presently syncing within .centos.org we hope to open this to mirror sync in the evening tomorrow. Please note that we'd like to embargo the tree till 22:30 UTC 13th May 2010. The rsync's are running with a reduced permission. We will bit-flip fairly early in the day, so most mirrors should get about 36+ hours to sync the tree, and then another 10 - 12 hours for the bit-flip to propogate through. 5.5 is just under 20G in size. Mirrors that carry the DVD will get about 29G. 5.4 will move to vault in about 2 weeks after 5.5 is released. Many thanks to all you guys who run mirrors for the project, its always appreciated. Regards, - KB
