I am running DNS bind 9.2.1 - presently i am experiencing a problem where it is not able to resolve DNS records that seem to be over in china and our hosted by mx.sina.net I am not able to send mail to greatmountain.com.cn or everesports.com Because my DNS server times out. When I issue a dig on these sites is when i see the timeout.
If i use www.dnsstuff.com
they seem to have the ability to find these sites... Can someone tell me what i should look for. It seems as if I can find most other sites in the states no problem, My DNS's have been working fine for the past two years.. this all of a sudden just started happenning on these Specific domains. I perfomed a reboot to clear cache but no change.
