The company I work for designs/builds data centers for airports all over the world and four years ago we started using Loadbalancer.org's loadbalancer virtual appliance. In these past four years I have only had to reach out to their support twice. The quick response and level of attention I received was like no other. I had anywhere from 1 to 3 support engineers engaged both times I submitted a ticket. I fly to sites to oversee the turning up of the systems and the pressure is always high, so quick response times and great attention for help speaks volumes about a company. Loadbalancer.org supplies a proven product and outstanding level of support.
