Ah bad link, here it is github.com/Azure/kimoji...
They have automatic failovers of primary to read replicas (and if old primary comes back online it will come back as a read replica). Since compute nodes are stateless this is easy for them to do. A mention of ringfencing but no details on it. Video has a nice animation of this.
