I was unable to find any issues so far. It seems like ZooKeeper does a great job at handling network failures.
This tool is deploying a ZooKeeper cluster on a cloud provider using Whirr together with Byteman [1] (attached to the JVM). Faults are injected by using Byteman rules. See this tutorial: https://community.jboss.org/wiki/FaultInjectionTestingWithByteman#what_is_fault_injection_testing I am planning to improve the tool to have the ability o inject arbitrary rules through the web UI. As an workload generator I am using a distributed queue implementation that's handling ConnectionLoss by retrying to post the message (duplicates are acceptable when measuring the latency).
