I am using the default settings with two gateway app and one traffic manager.
What I realized is that during the application gateway failure processes when a server goes down it shows the "bad gateway" error during the time to do what is normal, but the user notices the time out.
I know I can use a 502 error page, but I want a setup that will respond faster.
This also happens when the traffice manager identifies a problem at the application gateway and takes time to understand that it is degraded.
My fear is to make a configuration too short and cause other problems.
I want the opinion of you or someone who has already configured these times in practice to know what would be an ideal configuration and good practice.
