How redundant are the nameservers provided by Z3 Internet?
All nameservers provided by Z3 Internet, both your personalized nameservers and our anonymous nameservers are hosted on two separate servers operating on completely different networks. This ensures the highest availability DNS service. Your domain names will always be visible. Some hosts skimp and host both of your nameservers on one server. If that one server goes down, all of your DNS services would go offline, and no one would find your site. Our redundant configuration is not prone to such problems.
