+So far we have found 1 issue:
+
+* Sometimes the old/native servers can reach the service, sometimes
+they get a timeout
+
+In old calico notes on github it is referenced that overlapping
+Pod/CIDR networks might be a problem. Additionally we cannot use
+kubeadm to initialise the podsubnet to be a proper subnet of the node
+subnet:
+
+```
+[00:15] server57.place5:~# kubeadm init --service-cidr 2a0a:e5c0:0:cccc::/108 --pod-network-cidr 2a0a:e5c0::/100

+podSubnet: Invalid value: "2a0a:e5c0::/100": the size of pod subnet with mask 100 is smaller than the size of node subnet with mask 64
