Introducing cloud.microsoft: a unified domain for Microsoft 365 apps and services

Hi hkusulja, Thank you for the detailed feedback. For transparency, here are a few additional notes on what's coming and how we're planning to communicate about it: 

1. Services and applications are announced as migrated and available under the cloud.microsoft domain when they are ready for use by the public or when customers need to take specific actions to prepare their environment for their use. You are correct that Viva Engage was mistakenly added a bit before it should have been – nice catch! 
2. Admin Centers will migrate at various times; all will be subdomains under admin.cloud.microsoft.
3. There is no current timeline for SharePoint to move to cloud.microsoft. Ample notice will be provided before any change to SharePoint domains. Because Viva Amplify is a SharePoint service, it will follow what SharePoint does.
4. Cloud.microsoft domains which will require network administrators to make internal updates in advance, such as outlook.cloud.microsoft, are included as new network allow list entries on this page and in associated RSS feeds prior to the domains being in GA. This is by design and in preparation for the future transition of the applications.

I hope these clarifications are helpful. Please don't hesitate to reach out with any additional feedback you might have.
