I've seen so many servers fail because of the game server messing up.
Either the owner and developers are away doing stuff IRL and cannot get to a computer to notice their server has been offline for HOURS. This causes a lot of players to lose interest in the server they are playing. So I have created a way to switch to a backup server so if the primary server were to fail by either a game server null, ddos, or server crash, it will failover to your backup server with little to no downtime.
How it works:
Server 1 is running fine, no problems.
Tony get's upset because Owner will not give him what he demands.
Tony attacks your server causing it to go down.
Server 1 goes down, fails over to Server 2.
This should incrase uptime to upwards of 95%. You still need to do a server maintenance period one time a week to maintain your servers health. I would recommend a Sunday morning at 3:00 AM. This can also be automated. You also have updates you will need to do on your server. However, during maintenance period, you could simply failover to Server 2 to increase your uptime even more.
Not sure if this is worthy of a show-off or not. Thoughts?
If there is enough demand I will make a tutorial on how this is done.
