Alright... We have only one external ip, which obviously makes things hard... We have a cluster setup, but nothing in the tutorials explained how to set up any sort of failover? Our cluster setup is giving us issues though, like DNS records not sticking. getting errors like Code: CONFIGURATION ERROR 2018-09-21 14:28 : zone childrenofatom.church/IN: NS 'ns2.afraid.org.childrenofatom.church' has no address records (A or AAAA) zone childrenofatom.church/IN: not loaded due to errors. Even though I had rectified missing the period already. In other words, I'm sometimes having to go in and click an individual record and re save it, to make sure it sticks. And this happened yesterday. Code: 2018-09-21 20:31 miyagi.gethosting.today Warning Unable to determine a mapping path 2018-09-21 20:31 miyagi.gethosting.today Warning Unable to determine a mapping path 2018-09-21 18:22 miyagi.gethosting.today Warning Unable to determine a mapping path 2018-09-21 18:20 miyagi.gethosting.today Warning Unable to determine a mapping path Not sure what that means exactly So I guess this thread is about, what is the best: single external IP, two server configuration. And are these issues I should be worried about? I mean the DNS records is annoying, and it's causing issues with Mail I think. @Taleman had said he couldn't see my MX or SPF records using reverse DNS, but I'm not sure if he was doing gethosting.today, miyagi.gethosting.today or daniel-san.gethosting.today (which does not have a public IP) So this is becoming increasingly frustrating.
