Maintenance: Update on the primary DNS resolver

Meldungsnummer: 2020051910003871
Zeitraum: 20.05.2020, 4 - 5 pm
Betroffen: primary DNS Resolver
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’.
