# Multi-Region Deployment Configuration (LEGACY)

# IMPORTANT:
|
|||
|
|
# - This file captures earlier experiments with Dv2/Dsv6/DSv3 families and a
|
|||
|
|
# small set of regions.
|
|||
|
|
# - The **active, quota-safe 37-region Dplsv6 design** now lives in
|
|||
|
|
# `multi-region-global.tf` and is controlled via `enable_multi_region = true`
|
|||
|
|
# in `terraform.tfvars`.
|
|||
|
|
# - This legacy path is gated by `enable_multi_region_legacy` and should
|
|||
|
|
# normally remain **false**. Treat it as historical reference only; do not
|
|||
|
|
# enable it in new deployments.
