Managed instances are available during update operations but there is a short downtime caused by the failover that happens at the end of updates that typically lasts up to 10 seconds. The exception to this is update of the reserved storage space in General Purpose service tier which does not incur failover nor affect instance availability.

> Duration of a failover can vary significantly in case of long-running transactions that happen on the databases due to [prolonged recovery time](sql-database-accelerated-database-recovery.md#the-current-database-recovery-process). Hence it's not recommended to scale compute or storage of Azure SQL Database managed instance or to change service tier at the same time with the long-running transactions (data import, data processing jobs, index rebuild, etc.). Database failover that will be performed at the end of the operation will cancel ongoing transactions and result in prolonged recovery time.

Managed instances are available during update operations except a short downtime caused by the failover that happens at the end of update. It typically lasts up to 10 seconds even in case of interrupted long-running transactions, thanks to the [Accelerated database recovery](sql-database-accelerated-database-recovery.md).

[Accelerated database recovery](sql-database-accelerated-database-recovery.md) is not currently available for Azure SQL Database managed instances. Once enabled, this feature will significantly reduce variability of failover time, even in case of long-running transactions.
