Unable to delete nonresponding psql replica

[Grubenhund]

Hi!
After incident in europe-west-9 https://status.cloud.google.com/incidents/dS9ps52MUnxQfyDGPfkY
I have a replica in europe-west-4 stuck in "This instance is not responding" state. Attempting to delete it leads to "The attempted action failed, please try again. Tracking number: c4601340505015883 "

Is there a way do delete it? I understand that incident is still ungoing, but it impacts only europe-west-9 and this replica is in europe-west-4
Thanks in advance

I would recommend trying to delete the instance via Cloud Shell.

gcloud compute instances delete INSTANCE_NAME --zone ZONE_NAME --project PROJECT_ID --quiet

ERROR: (gcloud.compute.instances.delete) Could not fetch resource:
- The resource 'projects/.../-11-8a00472b-replica' was not found

It also isn't showing in 

```gcloud sql instances list```
