Hi, Our Customers get US mirrors while using our IPv6 subnets (range 2a04:92c0::/29) and UK mirrors while using our IPv4 subnets (range 185.42.223.0/24), while all subnets are used, and marked as GB. As a result of that IPv6 enabled host have very slow download speeds and use international connectivity while they could use local mirrors. curl -4 --silent 'http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=updates&infra=stock' http://mirror.bytemark.co.uk/centos/6.6/updates/x86_64/ http://mirror.simwood.com/centos/6.6/updates/x86_64/ http://www.mirrorservice.org/sites/mirror.centos.org/6.6/updates/x86_64/ http://mirror.vorboss.net/centos/6.6/updates/x86_64/ http://mirrors.vooservers.com/centos/6.6/updates/x86_64/ http://centos.muzzy.org.uk/6.6/updates/x86_64/ http://mirror.econdc.com/centos/6.6/updates/x86_64/ http://mirrors.ukfast.co.uk/sites/ftp.centos.org/6.6/updates/x86_64/ http://mirror.ox.ac.uk/sites/mirror.centos.org/6.6/updates/x86_64/ http://mirror.synergyworks.co.uk/centos/6.6/updates/x86_64/ curl -6 --silent 'http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=updates&infra=stock' http://mirrors.centarra.com/centos/6/updates/x86_64/ http://centos.den.host-engine.com/6/updates/x86_64/ http://mirror.vtti.vt.edu/centos/6/updates/x86_64/ http://mirrors.cat.pdx.edu/centos/6/updates/x86_64/ http://mirrors.kernel.org/centos/6/updates/x86_64/ http://centos.chi.host-engine.com/6/updates/x86_64/ http://mirror.metrocast.net/centos/6/updates/x86_64/ http://lug.mtu.edu/centos/6/updates/x86_64/ http://mirror.yellowfiber.net/centos/6/updates/x86_64/ http://repos.lax.quadranet.com/centos/6/updates/x86_64/ How to fix that ? I suppose that's something to do with geo IP database, can you fix on your end or shall we contact someone (which geo IP DB are you using in that case?) ? Thanks!
