Hi Sathish,

 

End users will face disconnection between 10:11:00 – 10:11:30 AM (for new connections if load balanced on faulty node + existing connections only when keepalive or active content is being sent)

 

For existing connections, it depends if the clients will try to resend the service request on the same node or not will depend on few factors (in sequence): a) Any special profiles like Persistence or OneConnect (HTTP) Profile, e.g.,if there is any persistence profile like source address, then request will come to the same node up to (Persistent session time out - 180 seconds) b) Load balancing Methods + Priority Group Activation

 

So answer will be as follows: 1. depends on keep-alive option or any active HTTP content being used for Virtual Service. 2 & 3. if the page reloads, then the client will try to reconnect with new connection which depends on a or b options.
