I've two servers running the same website. A is primary server and B is simply a mirror, and files from server A are constantly mirrored on B.
Now I don't have a automatic failover solution, whenever server A goes down, I have to point the domain's A record to server B and wait for the DNS to get updated. Takes quite a lot of time but the sites hosted on these servers are critical and shouldn't be down for longer than a few minutes.
I've heard about Dyndns? They provide automatic failover if one server does down, what I want to know is if I can do the same using Bind? And if it's possible to do it automatically? Without human intervention.
I don't want a round-robin solution, I want a atuomatic switchover if primary box goes down.
