Hi,
I cannot delete my old network that has no resources attached.
I get following error:
The deletion of the network failed. Error: Operation type [delete] failed with message “The network resource ‘projects/XXX/global/networks/default’ is already being used by ‘projects/XXX/global/networkInstances/v-2010886378-6962c6d4-2aea-4ab5-acd6-c030d281895d’”
Does this mean that it is in use by some Google’s peering to somethign where we cannot access?
Hello @Huy_Nguyen1,
I invite you to follow @DamianS’s answer on this thread.
The error means the network cannot be deleted because it’s still being referenced by a network instance (v-2010886378-6962c6d4-2aea-4ab5-acd6-c030d281895d), even if no visible resources appear. This could be due to internal Google-managed resources, like VPC peering, default routes, or auto-created instances that aren’t directly exposed. You’ll need to identify and remove all references or peering connections before deletion; otherwise, GCP won’t allow it.
The error indicates that the network can’t be deleted because it’s still referenced by a hidden or active resource, such as a VPC peering, default route, or internal Google-managed instance. To fix this, locate and remove all dependencies or peering connections linked to the network before attempting deletion, as GCP prevents deleting networks with existing references.
