    This was a Microsoft side issue:

    Root Cause

    There was a known issue which caused the Distributed Query Processor (DQP) to be stuck and stop functioning during activation. This caused the data warehouse to be inaccessible.

    To resolve the issue, the Backend Escalation Resources applied a fix and this action allowed the DQP to function correctly which in turn resumed all your data warehouse operations successfully.

     

    Resolved after contacting support.

Thank you for the reply, I have a ticket in with Microsoft support who are currently looking at the issue. We are UK South.

 

How would I go about refreshing the token from my end? It seems like whenever this issue occurs for other people it just goes away after a few days. I think we're 5/6 days in now.

Hi MOVC ,

 

If you want to refresh the token, just clear the browser cache and refresh the browser.
