We run bind9 on RHEL/CentOS and one of our international offices that has their own auth and caching servers cannot resolve lenovo.com for some reason. If that office uses google DNS it works but using their own DNS caching servers, it cant resolve. Commands dig and nslookup give a timeout. Although dig with trace is able to get to the final answer. Nothing in the logs indicate an issue. Also, this is the only address that we cant resolve, everything else works fine.
Can anyone advise/suggest any ideas? Thanks
