My website, [url removed, login to view], is loading slowly. It's probably a DNS issue. It's hosted on Hostgator, but DNS is hosted with [url removed, login to view] (use Google translate if you want to have a look at that site). The reason is that Hostgator is not allowed to host Danish domains (.dk). However, it takes from ~8-20 seconds to load the site the first time you enter the url. After that, pages load quickly. If you close the site and wait five minutes, it's still fast. But if you wait longer (maybe like a day, haven't tested exactly), first page to load is still slow. Hostgator support cannot replicate the issue. I can show you via Teamviewer from my location if you need to see or run some test (like tracert, ping or similar).
It could be a Joomla issue as well with the site, but I doubt it. You can upload a simple html page there if you want to test.
