I can understand that VIP's can sometimes be akward, ARP fails or even worse that VIPs won't be correctly released due to unknown stuff.
However I do wonder why they choose such a complicated thing instead of looking into something like BGP that would've replaced their ARP setup.
Also they should've probably tried to look into K8s since inside a cluster such problems do not exist.
(There you have the problem to have a good LB at the outside of your cluster)
