I’m facing an issue with the deletion of the default VPC network (that is automatically created when a new project is created). We do not need a default network on our project.
Operation type [delete] failed with message “The network resource ‘projects/rugged-abacus-218110/global/networks/default’ is already being used by ‘projects/rugged-abacus-218110/zones/europe-west2-b/instances/nbrt-7539272066822832128-p-europe-west2’”
I have checked compute instances, and we have none. I have checked other resources that could be using the network, but there doesn’t appear to be any.
This has left the default network in an inconsistent state as it can’t be deleted completely nor can it be restored.
Highly recommend to copy/paste this instance name at the Search field either at project or Org level. It should search through all resources and find anything related with provided name.
In my case it was a lingering VPC peering connection in my vpc. Once I deleted that I was able to delete the default VPC. “nbrt-” seem to refer to endpoints that are in the vpc for one reason or another.
In regards to the original question in this post, I believe nbrt refers to notebook runtime. Once all notebooks and any other resources using the VPC are shutdown, any lingering connections will eventually timeout.
