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.

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.
