Teleporting trough servers...

Hi guys, I just only have two servers, the main and the fallback one. My problem is that sometimes, the main server crashes and then, I'm going to expect the players to get to the fallback server, but hey, nothing happens, it just closes player connection with Connecting:ReadTimeoutException : null, so is there a plugin to teleport players when another server times out? Or what should I do?

NOTE: Main server doesn't really shut's down, it's the problem, it just shows crash log...
