MSSQL error 40613

Error 40613 means the Azure SQL database is currently unavailable. This is typically a transient condition caused by failover, reconfiguration, or a scale operation. Since it has lasted more than 12 hours, this is no longer a normal brief interruption.

Recommended actions:

1. Check the database health in Azure portal.
   • Open the SQL database resource.
   • Review Resource Health for any platform issue affecting the database.
   • Also check whether the database state is Online.
2. Check for service incidents during the affected period.
   • Review the Microsoft Azure Service Dashboard for outages around the time the failures started.
3. Retry with backoff from applications.
   • 40613 is a retryable transient connectivity error.
   • Production applications should implement retry logic instead of surfacing the error directly.
4. Use the session tracing ID if the issue persists.
   • The error message explicitly says to provide the session tracing ID when contacting support.
   • Because the outage has continued far beyond the expected brief window, capture the tracing ID {AA587236-93BF-4371-9507-E74259E5269D} and open an Azure support request.
5. If a Dedicated Admin Connection is being used, verify there is not already an active DAC session.
   • In Azure SQL Database, 40613 can also occur if another session is already connected through DAC.
   • Only one DAC session can connect to a single database or elastic pool at a time.

Relevant behavior for this case:

• Azure documents 40613 as: Database '%.*ls' on server '%.*ls' is not currently available. Please retry the connection later...
• Brief occurrences can happen during failover or scale operations.
• If the duration exceeds 60 seconds or there are repeated occurrences in a day, the documented guidance is to file an Azure support request.
