I am facing problems with the mydns with ispconfig3 in a remote server. The problem is my sites (eg http://www.thehumanape.org) are down on times although the server is up. Could not figure out any error message, too. Visitors report and I find sometimes that the site disappears even when I dig the site. When I ssh and check the servers all seem working fine, yet the site becomes unavailable. Any clue appreciated. Or do you suggest me to migrate to BIND9? Any hints to migrate to BIND9 from mydns with ISPConfig3 in Centos5? Thanks!
