Betroffen: primary DNS Resolver gwdu01.gwdg.de 18.104.22.168
Auswirkungen: No resolution of DNS queries by the primary DNS resolver and no new DHCP leases for 1 minute
Due to critical security gaps, our DNS resolvers unfortunately have to be updated at short notice and outside the maintenance window. Since the primary resolver is a cluster of 2 systems, a short ‘hiccup’ is only to be expected when ‘panning’.
