[Driftstörning] Resolver/Nameserver maintenance on May 15th and 16th.

[Göran Bengtson]

An application upgrade is needed on our resolver system
(cache-only nameservers), res1.chalmers.se/(129.16.1.53,2001:6b0:2:1::53)
and res2.chalmers.se/(129.16.2.53,2001:6b0:2:2::53).

The upgrade is planned for May 15th (res2) and May 16th (res1), starting
at 17:00. The impact on the service is expected to be low (in the order
of seconds).
