Hi all, Sometimes our caching nameservers have trouble with mirror.centos.org. The reason is probably because pdns2.centos.org is down, and pdns3.centos.org is answering queries from the wrong ip-address it seems: $ host -t NS mirror.centos.org mirror.centos.org name server pdns2.centos.org. mirror.centos.org name server pdns1.centos.org. mirror.centos.org name server pdns3.centos.org. $ host mirror.centos.org pdns1.centos.org. Using domain server: Name: pdns1.centos.org. Address: 216.7.183.116#53 Aliases: mirror.centos.org has address 216.7.183.116 $ host mirror.centos.org. pdns2.centos.org. ;; connection timed out; no servers could be reached $ host mirror.centos.org. pdns3.centos.org. ;; reply from unexpected source: 63.135.110.10#53, expected 63.135.127.184#53 ;; reply from unexpected source: 63.135.110.10#53, expected 63.135.127.184#53 ;; connection timed out; no servers could be reached The last one can easily be solved by setting local-address. Hope this info is useful to anyone.
