Time: 28.02.2019, 17:00 Uhr – 17:30 Uhr
Affected: secondary nameserver ns2.gwdg.de, 134.76.33.21
Impact: ca. 5 min. outage of name resolving from ns2

We update the secondary name server of GÖNET, ns2. Many users set this up as their second resolver.
Since we have to reboot the server during the update, there will be a short outage in name resolving by this machine.

The primary DNS server gwdu01 is not affected, so you most probably will not notice the outage.

We unfortunately have to update the server for the second time this month due to critical security updates.
