  Does anyone know what load balancer product this is?  Since it is using DNS, I assume is one of these global slb things that tries to do clever things with DNS  (ie.  3 second TTL).  There do seem to be a lot of half-baked products out there that "appear to work", but don't really.  But in case, it is not clear whether they set it up properly, or whether it is just broken.
