  1. Press CTRL + F5 several times. In this way you'll delete the cookies in your browser and the page will be reloaded without any previously stored data in browser.
  2. Empty the DNS cache of your local computer. This way you'll make your laptop to update the server IP and other location details of d-nb.info.
