Resolved: ns1.citexnode.de and ns2.citexnode.de have been running stably for almost two hours and are now also monitored on this status page. Domains can be switched to our nameservers again.

Fixed: ns1.citexnode.de and ns2.citexnode.de are answering again. ns2 now runs at a different provider than ns1, so a single data center outage cannot take down both. The affected domain resolves again. In addition, when switching a domain to our nameservers, the dashboard now creates the zone beforehand and carries over the existing DNS records, so the registry accepts the change and nothing is lost. We keep monitoring the situation.

Cause identified: the addresses ns1.citexnode.de and ns2.citexnode.de currently do not point to our nameservers, and the second nameserver was still running on a server that has since been shut down. Domains already set to ns1/ns2.citexnode.de therefore do not resolve. We are setting up a new second nameserver at a different provider, correcting the addresses and loading the zones of the affected domains.

Switching a domain to our nameservers ns1.citexnode.de and ns2.citexnode.de currently fails: the registry rejects the change because the nameservers are unreachable for it. We are investigating the cause. Domains using other nameservers are not affected.
