Setting up a new server and it is getting some weird issues, I used pingdom to check the uptime and I am getting a downtime of 15 days per month or 745 outtages per month. I believe it might be the server configuration but I have no idea what to check. csf does not seem to block these people in the blocked ips table so I don't belive that is the issue. Any logs I should check, or what to look for? I have never had any issues from other countries, the server is mostly visited by the US. Thanks! Apache WHM 11.30.5 Cpanel Here is the error I am getting, Too few IPv4 Name servers http://dnscheck.pingdom.com/?domain=markspixel.se
If they are not available to some ISPs and not others sounds like a routing issue. If this is indeed whats going on you will need to contact your datacenter. Have your clients that can not connect to the server and do a trace route this way you can see where it fails. Let me know if you need help. Good Luck!
