Improvements and issues that are fixed

Faster server provisioning & improved disaster recovery for Azure File Sync server end pointsWe’re reducing the time it takes for the new server endpoint to be ready to use. When a new server endpoint is provisioned, it could take hours and sometime days for the server to be ready to use. With our latest improvements, we’ve substantially shortened this duration, ensuring a more efficient setup process. The improvement applies to the following scenarios, when the server endpoint location is empty (no files or directories):

• Creating the first server endpoint of new sync topology after data is copied to the Azure File Share.
• Adding a new empty server endpoint to an existing sync topology.
