Third AZ in EU (Frankfurt) Region

Customers are now able to use three Availability Zones (AZs) in the EU (Frankfurt) Region. We launched the third AZ in response to continued growth in the use of AWS in Germany and to provide customers with additional flexibility to architect applications across multiple AZs in Germany for high availability and fault tolerance. This launch brings AWS’s global AZ total to 43 AZs within 16 geographic Regions around the world.
