There's a slight (firewall?) issue with your mirror, though: $ curl -6v http://dedic.sh/centos/timestamp.txt * About to connect() to dedic.sh port 80 (#0) * Trying 2001:67c:1688:b::... * Permission denied * Failed connect to dedic.sh:80; Permission denied * Closing connection 0 curl: (7) Failed connect to dedic.sh:80; Permission denied Maybe this could be fixed? Once the issue is fixed, your mirror will no longer be listed as failing on http://miuku.net/ipv6reach/ (the list is updated only every three hours).
