Failover on surf on the go

Why is 5 the lowest you can go on the health intervals and retries?! I would like a faster switch over once it confirms the initial connection has failed? So is 5sec interval x 5 retries as low as you can go? Why not offer instant switch over, That’s 25sec right there…

This is the optimum design. Please imagine if the primary link not stable (intermittent), and we need the failover to be triggered immediately. This will cause flapping between primary and backup link. Hence, we need to keep some health check retries within defined interval to confirm the condition of the primary link. If it is bad within the health check interval, then only failover to backup link.

Hope this clear your doubts.
