It seems the problem is with the DNS configuration. What is your domain name ? Please check the DNS records using intodns and correct them accordingly.

| Posted by Maikon, 01-24-2011, 01:34 PM | | actually intodns reports nothing wrong. and sorry cannot provide the url due to adult content. i asked user to provide traceroute but they cant says it cannot be resolved but i did the mtr to their ip through the server nothing is wrong and also the visitors can visit the server ip just fine just the domain issue. I dont get why some can access and some dont

If they can trace it and just not resolve it then it is a DNS issue. If they cannot traceroute it and you host dns locally that would explain being unable to resolve it. Compare a good trace versus a bad, it sounds like a local issue on your server.
is "iptables -L -n" empty?

| Posted by Maikon, 01-24-2011, 02:01 PM | | well they can trace the ip but not the domain itself. and firewall is disabled now. Actually doing a traceroute from example two singapore users who one cannot access and one can have their traceroute to the server ip almost indentical while when both tried traceroute to the domain one isnt working at all.
iptable has been flushed several times and not banning ips
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
but haing 800 complaints daily seems this is increasing issue now. Even i cant access my own website.

No warnings even? Some of the issues intodns presents as a warning (eg. stealth nameservers) can cause the symptoms you describe.
Edit: Another thing to check is the dns on your nameserver domain(s). So if you were using ns1.example.com as your nameserver you should run the intodns check on example.com.
