[Driftstörning] Network maintenance on February 9th, starting at 17:00.

[Göran Bengtson]

We must upgrade the software in the routers in the computer center. This
work is planned for February 9th, starting at 17:00. It may take up
to 1 hour.

The routers are redundant and the upgrade will, if all work as expected,
not cause any major service impact. However, in case of major problem,
most central services (network, as well as other) are at risk.

Four single-attached connections/services/systems WILL loss connectivity 
(in the order of 5 to 10 minutes).
They are the c3se system amy.c3se.chalmers.se and three IT Services systems
(isis.ita.chalmers.se - the old backup server), ewing.ita.chalmers.se and
sccm01.ita.chalmers.se - installation servers).
