I've noticed several US mirrors that are out of date. I've had to switch mirrors twice now but there seems to be a master mirror somewhere that's stuck on an August 3rd timestamp. These are ones that have this timestamp as of 12:30 UTC http://mirrors.usc.edu/pub/linux/distributions/centos/timestamp.txt http://ftp.linux.ncsu.edu/pub/CentOS/timestamp.txt http://centos.cogentcloud.com/timestamp.txt http://mirrors.cat.pdx.edu/centos/timestamp.txt http://mirror.dhsrv.com/centos/timestamp.txt http://mirrors.versaweb.com/centos/timestamp.txt -Chris
