Are all the users with problems in the same location, or spread out among
different DNS servers?
There's lots of reasons that could be going on depending on who's having the
issues. DNS servers are often set to only recurse routes for certain IP
address ranges (so if you change Ips, you may need to updated named.conf (if
a unix box)).
Otherwise, for global reachability, people should look up your domain with
the root DNS servers and presumably get the same information for your
authoratative servers. As long as there's no ACL issues reaching them from
certain Ips, life should be good.

Hello,
I know the topic may be not right to put over here. But i still do hope

my company's DNS name from Internet, but they could brower other sites. Only
some users have this problem. Anybody aware any DNS server issue in
Internet? Where should i looking for the information?
Thanks,
Joshua
