junz Posted October 18, 2022 Posted October 18, 2022 Good morning all, I am having an issue with our school website which I am hoping that you all might be able to help with. The school website has the same domain as our internal domain (I know a bad idea) and when accessing the school website from within the school network it takes a while to load. I have added a WWW and an A record to our internal DNS pointing to the new site but it hasn't helped much. We used to access the website fine when we were with our old website provider but ever since we have moved to our new website we have had this issue. Any help is much appreciated.
leeshellard Posted October 18, 2022 Posted October 18, 2022 Does the website load ok if you browse to the ip address?
junz Posted October 18, 2022 Author Posted October 18, 2022 Does the website load ok if you browse to the ip address? When I go to the IP address there is a message that states "This is the default server vhost this site's domain name is either not yet pointed or is still propagating. Propagation may take up to 72 hours. Please check back later.".
Foresthippy Posted October 18, 2022 Posted October 18, 2022 I wouldn't expect IP address to work as the host probably has numerous websites on it - you'd probably need to add the domain name on the end - i.e. https://x.x.x.x/yourdomain.com or similar. Your host will probably have a direct access URL you can use. Have you checked that you only have one www record in your forward lookup zone?
mavhc Posted October 20, 2022 Posted October 20, 2022 I'd try to determine which part is slow. Use nslookup to test DNS, and curl to test downloading the HTML
Rooty Posted October 23, 2022 Posted October 23, 2022 As above, try using curl from an internal machine with the '-v' flag to put it in verbose mode.
FN-GM Posted October 24, 2022 Posted October 24, 2022 Do you have a proxy server in the mix that could cause an issue?
junz Posted October 24, 2022 Author Posted October 24, 2022 I'd try to determine which part is slow. Use nslookup to test DNS, and curl to test downloading the HTML I have used nslookup and am getting the IP address of the server. I have also used curl -v and when using http://www.domain.co.uk,the site is brought up immediately but when using https://.domain.co.uk it tries to go out over out local DNS via port 443 and fails.
junz Posted October 24, 2022 Author Posted October 24, 2022 Do you have a proxy server in the mix that could cause an issue? No, we have filtering but I have made sure the site is blocked. I think it is something to do with the fact that our interal domain is the same as our website domain however the only caveat is that it has only become an issue since we have moved website providers.

So is the difference between http and https or http://www.domain.co.uk and domain.co.uk?
robintech Posted October 28, 2022 Posted October 28, 2022 Browser dev tools is useful like Chrome F12 - Performance, Console, Network usually has something in Red showing up.
robk Posted October 28, 2022 Posted October 28, 2022 Make sure your website is being served as "www.domain" not just "domain" if its the latter then it will conflict with your onsite DNS entries for your Domain controllers. We hit a similar problem when we had a website redesign.

We hit a similar problem when we had a website redesign. This sounds like our issue. Do you know how you went about resolving it? Is there some instructions that I can pass onto our website provider? Thanks in advance - - - Updated - - - So is the difference between http and https or www.domain.co.uk and domain.co.uk? After performing test using both it looks like both http and https the same.
robk Posted October 28, 2022 Posted October 28, 2022 In our case, our new website was designed to redirect www. to which on the wider internet meant that an A record for was the website hosting. I had to ask our hosting to swap the site from to www. and it was fixed very quickly. You could prove thats the problem by adding an ip address for into your hosts file, and then try and browse the site "off site".
