See below the speedtests for my old ISP and new ISP.
I already written 2 scripts that allow me to change from one connection to the other. The next step is to write a script, conjobed, that will check for internet on main connection (new ISP), switch to secondary (old ISP) if failed, and then switch back to main when it’s back.
And finally, I will have to find some DNS software similar to the one google uses. so that when you access my server it will use the IP that is online 🙂
