I have some websites that are not resolving for SOME users using a certain internet provider. Two of the websites are on totally different servers. If people try to get to the websites from their home, using the local internet provider, the website will try for a few minutes and then say the website could not be resolved. It doesn't matter what system they use (mac, pc, linux) or what browser they use. The oddest part is that when they use their cell phone data plan they can get to my websites just fine.

Two of the websites are http://www.cstx.gov and http://click2gov.cstx.gov/Click2GovCX/index.html

It seems very random who can and cannot view the websites. Some people may not be able to view it for a few days and then the issue will resolve for them. Others still can't see the sites after MONTHS....

I cannot access either of those two websites from the UK, over broadband or cellular. DNS resolution is fine for both sites, however there is no connection on port 80. Telnet to either IP address gets no SYN/ACK response from the server.

If other people are able to access the site without issue then there is most likely an overly restrictive access control rule somewhere which is breaking things.

You say that the websites are not resolving. If this really is the case (impossible to say without the actual error messages) then its nothing to do with your server software, it's a DNS problem. Indeed, according to pingdom, "Delegation not found at parent". More specifically, the nameservers for cstx.gov aren't offering any information about www.cstx.gov
