Help Center\Websites often rely on services and resources hosted on multiple external domains. Instead of hosting the website on a single server, third-party services are often integrated which load components from different URLs. For this reason, when attempting to permit access to a website, failing to permit access to all associated domains may result in the website's inability to load and/or function correctly.
Below are some commonly permitted websites and the associated domains that should also be included in a Web Control permit policy to enable the website to function correctly.
