Hi Eliezer, The DNS we are using is the ISP default for external, our internal domain DNS for internal. Nslookup works for all tests. I would like to update to the latest stable, but I am concerned of breaking the current setup. It took a little work to get it working correctly particularity on the multiple authentication methods working with our domain and trust. I support what has been said - to check the logs. This will likely take time as I cannot reproduce this issue on demand - and I think users are starting to not report the issue and just living with it (or it is not getting all the way to me at least). I will have to get lucky at some point on my computer and look into it then. Could squid be getting mixed up when mulipule https requests are to the same address (e.g. https://google.com.au)?

You can see there if the proxy is trying for example to reach an IPV6 address (by mistake). Also to make sure there is an issue you can use specific exception like the cacheadmin acl you are using to allow the cacheadmin access without authentication for the basic test. Also you are indeed using the latest CentOS 6.5 squid but since the current stable version is 3.4.8 you should try to upgrade(to something else then 3.1) due to other issues. The issue can be a network or dns related issue which was not detected until now. Please first make sure that the access.log and cache.log files are clean for errors or issues. What dns servers are you using?
