On Friday, December 11th, from 1200 and 1400 CST (Saturday, December 12th 0500 to 0700 AEDT), the Cloud Operations team will be applying updates to the APAC - Enterprise One Australia Datacenter (AWS) Power BI Report Server farm. During this time all reporting will be unavailable for customers v15+.
This is just a change to the authentication code and not a change to the version of PowerBI running on the farm.
If you do experience any issues with existing Power BI content please submit a case via https://support.planview.com.
Thank You,
Cloud Operations
