subnet-allocations

Summary

Section titled “Summary”

This document tracks the subnet allocation across multiple infrastructure projects related to GitLab.com. Any project that requires centralized monitoring or maintenance from ops runners should be configured to not overlap with the gitlab-ops project for network peering.

Reserving a new subnet

Section titled “Reserving a new subnet”
  • Update this MR with a new allocation, pick a row that has AVAILABLE GCP, if needed we can start using previously allocated subnets for Azure
  • Larger subnets can be split into smaller ones, if necessary
