Hi, We host a mirror for centos in India @ http://mirrors.hns.net.in/centos/ The mirror is IPv4 and IPv6 capable for quite a while now. I was just trying to update some new server (with IPv6 connectivity) and these servers are only picking up mirrors from outside India only for IPv6 connectivity. IPv4 Connectivity seems fine. Can you please check and revert. $ curl -6 "http://mirrorlist.centos.org/?release=6&arch=i386&repo=os" ftp://mirror.aarnet.edu.au/pub/centos/6/os/i386/ ftp://mirror.bytemark.co.uk/centos/6/os/i386/ http://ftp.hosteurope.de/mirror/centos.org/6/os/i386/ http://mirror.steadfast.net/centos/6/os/i386/ http://centos.mirror.iweb.ca/6/os/i386/ http://mirror.as24220.net/pub/centos/6/os/i386/ http://ftp.jaist.ac.jp/pub/Linux/CentOS/6/os/i386/ http://mirror.us.leaseweb.net/centos/6/os/i386/ http://mirrors.coreix.net/centos/6/os/i386/ ftp://ftp.free.fr/mirrors/ftp.centos.org/6/os/i386/ $ curl -4 "http://mirrorlist.centos.org/?release=6&arch=i386&repo=os" http://centosmirror.go4hosting.in/centos/6.3/os/i386/ http://mirrors.hns.net.in/centos/6.3/os/i386/ http://ftp.iitm.ac.in/centos/6.3/os/i386/ http://mirror.nbrc.ac.in/centos/6.3/os/i386/ http://centos.aol.in/6.3/os/i386/ http://mirror.dhakacom.com/centos/6.3/os/i386/ http://mirrors.ispros.com.bd/centos/6.3/os/i386/ http://centos-hcm.viettelidc.com.vn/6.3/os/i386/ http://mirror-fpt-telecom.fpt.net/centos/6.3/os/i386/ http://centos-hn.viettelidc.com.vn/6.3/os/i386/ $ dig +short mirrors.hns.net.in msync05.hns.net.in. 111.91.91.34 $ dig +short aaaa mirrors.hns.net.in msync05.hns.net.in. 2401:4800::111:91:91:34 -- Regards, Ripunjay Bararia Honesty Net Solutions (I) Pvt Ltd Mumbai, INDIA
