I have 2 computers running ispconfig. Each of them have 2 ethernet connections. Each of the connections is for a diferent internet provider. It would be very helpfull if the dns records created by ispconfig could consider a "round-robbin" configuration. This would give an extra extrength to the server in case one of the providers have a problem.
It doesn't. 50% of the people visiting your site will not get a connection anyway. Round-robin not automatically scwitches to an alternate IP address. There are plenty discussions on the Internet, describing how you could setup a failover environment. Having two providers and thus two routes is IMHO not a good idea.
