Can you check from inside the pods whether the API servers answer? kubectl exec ....
In other words: is it a network problem?

Yep, oc -n openshift-apiserver exec <pod name> -- curl -kLvs https://localhost:8443 works fine

It's an MTU problem; the nodes have an mtu of 1460. We need to fix this, either in the network operator (someday) or the installer (easier)

How would you propose the installer fix this without changes to the operator?

It was a wrong MTU on GCE which was breaking us

A couple ways to do this, but for GCP, the SDN mtu will always be 1410. We already have https://jira.coreos.com/browse/SDN-250 to figure out the MTU story in a sustainable way.
