Currently logstash's kibana interface is defined directly in varnish as a pool of randomized backend hostnames. There should be a real service hostname for the internal service like logstash.svc.eqiad.wmnet, which is defined in LVS with pybal controlling the pooling of the 3x backends, and then varnish's configuration should be updated to use that hostname rather than enumerating the backends directly. This involves a handful of complex puppet changes and LVS new-service deploys are always a bit "special" (requiring careful manual restarts).
