Loadbalancer.org is a great company to work with and they make a great product. Since introducing an HA pair of their virtual appliances into our environment, we have experienced greater uptime and eased the burden of performing maintenance on systems that were either not highly available, or depended on a basic DNS round-robin load balancing system. The support they provide is amazingly prompt, courteous, and they are experts on their product. They listened to a unique need I communicated and produced a custom configuration to accommodate exactly what I was asking for. Of all the vendors I deal with, Loadbalancer.org ranks right at the top of those that are a pleasure to do business with.
