Time: am 25.04.2019, 4:30 – 5:00 pm
Affected: DNS queries to gwdu01 and ns2
Impact: DNS queries cannot be processed for a very short time (<10 sec)

Background:
Due to a very important hotfix of our DNS server, DNS queries to gwdu01.gwdg.de (134.76.10.46) and ns2.gwdg.de (134.76.33.21) cannot be processed for a very short time.

Downtime for each server will be under 10 seconds.
For the most users this downtime should not be noticed.
