I assume you meant mirrors.m247.ro, which seems to be up to date and its DNS records are also OK. It is also listed as OK on http://mirror-status.centos.org/ and it is listed on http://www.centos.org/download/mirrors/ However, what might be a problem is that your mirror is currently not included in the output of http://mirrorlist.centos.org/?repo=os&arch=i386&release=6&cc=ro when the list is requested over IPv6. The reason for this is that your mirror does not seem to be reachable over IPv6 from the primary mirror checker node. The primary node is located at Gandi. Here's a traceroute6 to your mirror from a nearby server at Gandi: $ traceroute6 -A -q1 mirrors.m247.ro traceroute to mirrors.m247.ro (2a04:9dc0:0:8::2), 30 hops max, 80 byte packets 1 2001:4b98:dc0:41::250 (2001:4b98:dc0:41::250) [AS29169] 0.825 ms 2 p254-core3-d-ip6.paris.gandi.net (2001:4b98:1f::c3d3:249) [AS29169] 3.184 ms 3 ibr01-ve26.lndn01.occaid.net (2001:7f8:4::7577:1) [AS5459] 8.203 ms 4 * 5 2a01:300:1:106::2 (2a01:300:1:106::2) [AS9009] 53.319 ms 6 * 7 * 8 * If you want to do a traceroute6 to the other direction, villisika-v6.miuku.net might be a good target. Your mirror will be included on the list again automatically once this problem has been corrected. The nice folks at Gandi can probably help you with resolving the routing issues.
