+	}
+
+	migrated, _ := strconv.ParseBool(req.Machine.Annotations[migratedMachineAnnotation])
+	projectID, serverIDs, err := p.serverIDsForMachine(ctx, req, projectIDFromSecret, providerSpec.Region, migrated)


Why does this return multiple serverIDs?

nschad · 2026-09-07T19:02:27Z


-		// Parse ProviderID to extract projectID and serverID
-		projectID, serverID, err = parseProviderID(req.Machine.Spec.ProviderID)
+func (p *Provider) serverIDsForMachine(ctx context.Context, req *driver.DeleteMachineRequest, secretProjectID, region string, migrated bool) (projectID string, serverIDs []string, err error) {


Suggested change

func (p *Provider) serverIDsForMachine(ctx context.Context, req *driver.DeleteMachineRequest, secretProjectID, region string, migrated bool) (projectID string, serverIDs []string, err error) {

func (p *Provider) serverIDsForMachine(ctx context.Context, req *driver.DeleteMachineRequest, projectIDFromSecret, region string, migrated bool) (projectID string, serverIDs []string, err error) {

Add massive docstring. Explain in detail what this does

nschad · 2026-09-07T19:03:48Z

-	if serverID == "" {
-		klog.V(2).Infof("Server is already deleted for machine %q", req.Machine.Name)
-		return &driver.DeleteMachineResponse{}, nil
+func (p *Provider) deleteServers(ctx context.Context, projectID, region, machineName string, serverIDs []string) (bool, error) {


Why plural? Also you return out of function instantly as soon as you get a 404, what about the other serverIDs?

nschad · 2026-09-07T19:04:17Z

-	// Call STACKIT API to delete server
-	err = p.client.DeleteServer(ctx, projectID, providerSpec.Region, serverID)
+func (p *Provider) deleteMachineNICs(ctx context.Context, projectID, region, networkID, machineName string) (bool, error) {
+	nics, err := p.client.ListNICs(ctx, projectID, region, networkID)


Same as above.
