You can leverage the Microsoft 365 Public Content Delivery Network (CDN) capability in Appspace SharePoint Intranet , so the static assets (Javascript/CSS/image files) will be served from the Office 365 CDN service.
In order to enable this for the Appspace SharePoint Intranet static assets, please execute the following script, provided with any Appspace SharePoint Intranet cloud installation, for every Appspace SharePoint Intranet site collection in your environment:
.beezy-EnableCDN.ps1 -SiteCollection <site_collection> -ConnectionCredentials <PowerShell_credential_for_site_collection_admin>
After executing the script, please wait 30 minutes approx. for the changes to apply. After this period, you should start seeing the Appspace SharePoint Intranet assets served from the URL https://static.sharepointonline.com (you can use your browser’s developer tools to verify it).
