[Driftstörning] Nameserver maintenance on July 18-22

[Göran Bengtson]

Software/hardware maintenance of planned for our authoritative nameservers
on July 18-22. We have three on-site servers, and we will only work on one
at a time.

No DNS-service impact is expected for users. However, the systems are also
NTP-servers. Correctly configured clients use more than one of them and will
not experience any service problems/downtime.
