Hello there. This is the haproxy user mailing list. It is received and read by a wider range of users across the world, many of whom read it in an individual capacity. If you want *commercial* support, then here is a link to organisations which provide it: https://www.haproxy.org/#supp > We all know that when we configure HAProxy in the Active-Passive manner then > there is a VIP.

This is *entirely* the concern of the technology and methods you use to create the VIP across multiple haproxy instances in your different sites. It isn't under the control of haproxy, which deals with failover of the *backend* services you're load balancing. Failure of an entire loadbalancer, and how your setup deals with that, is *100%* a concern of the technology (not haproxy) with which you've chosen to implement resilience. People *might* be able to assist on this list if you gave some more detail about the technologies you're using. HTH! J
