I have 3 connections balanced on ‘Fastest response’ method.
Now one connections runs out of traffic and ISP blocks it. Two remaining connections still work. What ‘Fastest response’ should do? It even does not need any health checks - just put traffic on that one who responds faster.
What ‘Fastest response’ practically do? Hang! Nothing works!
Looks like algorithm’s waiting to have responses from all selected connections until it choses the fastest one. And obviously will wait forever to get response from non-healthy connection. I don’t have any other explanations. Once I manually disconnect problematic connection, everything works again.
