Hi,

Yes, it seems there is an issue wrt ipv6 mirrorlist node, and I
already asked to KB (managing that node) to have a look at that .. I'd
guess it's a problem with the maxmind GeoIP DB not being up2date on
that node (as it works fine on the ipv4 mirrorlists nodes)

Such report would be good to have on bugs.centos.org though, so that
it can also be tracked

Cheers,
