So is there a hosting setup where you have your servers say at host "A" and at the same time have a mirror of the server at host "B", and at host B the server has an application that auto detects any downtime at host A and somehow takes over.

Right now one of my main sites is having DNS issues and would be nice if Host "B" would kick in, and even nicer if host "A" would fix their shit!

That's how things would work, however you need a proper load balancer that will distribute the traffic to both systems. Then if host "A" goes down, the load balancer notices this and sends the traffic to only host "B" until host "A" comes back.

So in your case you may just have round-robin DNS setup which doesnt have any kind of error detection so it wont automatically switch that traffic for you.

If you need more information hit me up on icq at 36837470.

Your looking for a hosting provider that probably has a F5 3dns setup or some sort of DNS load balancing that would detect a down host.. We don't have this but we do run F5 BigIP's in HA. This allows you to have two machines running and both serving content 24/7/365 and allows one to die/fail and the other would just take 100% of the load. Usally we design these setups n+1 (meaning a single server can take full load but we do one more just incase one goes down) for small application but have gone as far as n+3 on some of our larger clusters

icq me for details if I can't provide you with a solution I'll just suggest the best way to do it.

This is how google type load balancing is done:

Most hosts have a different version.
