Account failover: Customer-initiated storage account failover is now generally available, allowing you to determine when to initiate a failover instead of waiting for Microsoft to do so. When you perform a failover, the secondary replica of the storage account becomes the new primary. The DNS records for all storage service endpoints—blob, file, queue, and table—are updated to point to this new primary. Once the failover is complete, clients will automatically begin reading from and writing to data to the storage account in the new primary region, with no code changes. Customer initiated failover is available for GRS, RA-GRS, GZRS and RA-GZRS accounts. To learn more, see Disaster recovery and account failover
