Hi,
HTTP: http://centos.linuxmirrors.ir Sync schedule : Every 4 hrs Bandwidth : 100Mbps at the moment Location : Europe Region : France Sponsor : Mohammad Oshaghi Sponsor URL : linuxmirrors.ir IPv4 address to authorize : 51.254.77.128 Email contact : mroshaghi@gmail.com Mirroring AltArch : No
Hi, looks like linuxmirrors.ir is having DNS problems. ns1.linuxmirrors.ir and ns2.linuxmirrors.ir both point to 51.254.77.128, and querying that server with a "dig @51.254.77.128 ns linuxmirrors.ir" gives me a SERVFAIL. I can't verify the mirror because centos.linuxmirrors.ir can't be found from DNS.
As an aside, it would be best practice to have the 2nd DNS server on some other host, preferably in some other network.
