[Driftstörning] Emergency maintenance of cache only nameservers.

[Göran Bengtson]

A software upgrade is needed on our cache-only nameservers (resolvers).
(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 maintenance is planned for:
27/2, starting at 17:00, for res2.chalmers.se
28/2, starting at 17:00, for res1.chalmers.se

Only minimal service impact is expected.
