- In order to add an AZ(s) to a VPC, you would create new subnet(s) from existing space in your VPC's CIDR block, choosing the desired AZ in the process
- If your VPC has run out of address space, you would need to either delete some subnets, or add secondary CIDR block to your VPC. We have a guide on adding a CIDR block here: https://aws.amazon.com/premiumsupport/knowledge-center/vpc-modify-cidr-more-hosts/
- This process does not involve any downtime.
