Azure SQL Server Database Error: 18456, Severity: 14, State: 1
Azure is having a pretty major outage right now!


  Microsoft has warned that a "subset of customers in South Central US"
  may experience Azure problems today after cooling issues sent the
  servers scurrying for the shutdown button.
  
  The warning was first raised by Microsoft at 09:29 UTC as pretty much
  everything in the South Central US region went offline thanks to a
  temperature spike that caused servers to automatically shut down to
  avoid damage.


I'd suggest following @AzureSupport to stay updated.


  Unfortunately, the Azure support website is down so I can't investigate further.


Is a pretty good clue as to what's going on.
