Microsoft Azure has announced that Public IP addresses are now zone-redundant by default. This significant upgrade enhances the reliability of inbound and outbound internet connectivity for your Azure resources. Effective immediately, unless a specific zone is selected during deployment, Standard Public IPs will automatically benefit from zone redundancy, offering improved availability and resilience for services such as Virtual Machines and Virtual Machine Scale Sets. This update marks a major step forward in ensuring consistent and dependable network performance.
