Your DNS cache stores the locations (IP addresses) of web servers that contain web pages which you have recently viewed. If the location of the web server/site changes before the entry in your DNS cache updates, your site will still load from the old location. Some clues for this could be 404 errors or changes that you make not appearing. Those can indicate that your DNS cache needs to be updated to redirect towards the new location.
To check what DNS information your site is currently resolving to, please use our DNS tool located here: HostDime DNS Tool
You can also use a proxy tool such as HostDime Proxy Test in order to test a connection from your location to a website without using your local DNS Cache
