    Cluster and HA over WAN

    Hello, I have been reading for a long time about the feasibility of being able to install a cluster of 3 servers in different locations linked together by VPN. And I suppose that it is highly inadvisable to establish a cluster connection with a latency of 60-70 ms. Does anyone have a similar...
