Azure Storage account failover is now generally available
Published date: 17 June, 2020
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 and 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 the Storage account and writing data to it 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, read the documentation.
