Hi Ilo, To my knowledge a real server failing a health check done by an agent such as ldirectord/keepalived is pulled from the LVS table.
This will break any established connections to this server. A new connection should then start on a remaining live server on the next click/refresh for something like a web application or next connection retry for something else. How this affects your app/users depends on your application design, mostly HTTP sessions would be fine while things like RDP/SSH/HTTPS would require you to reconnect/re-authenticate.
