Spun a pair of these up in HA in Azure and ran into some challenges due to heartbeats getting lost and the load balancers going into split brain mode as Azure is noisy and unreliable for UDP Traffic. I engaged lb.org support and they have been absolutely wonderful and a breath of fresh air. Very knowledgeable, very helpful and I cannot say good enough about the people on the other end of the phone as the experience has been very good so far. The actual solutions we're load balancing for work with relatively little effort and I'm very happy with my deployment thus far
