[vsnet-grb-info 3168] GCN outage tomorrow

[GCN Circulars]

All GCN Sites,                                     25 Apr 06

GCN DOWN-TIME TO SWITCH TO A NEW OPERATING SYSTEM

(This is going to all Notices & Circulars customers -- apologies for duplicates.)

The GCN System (both Notices and Circulars) will be off-line tomorrow
Wednesday 26 Apr 2006 from 14:00 to 15:30 UT.

NASA has issued a new set of computer security requirements.
The version of RedHat LINUX that GCN is curently running under
is no longer on the approved list; so I have to upgrade.
GCN Notices & Circulars has already been ported and tested on the new OpSys,
so the transition should go smoothly.  90 min has been allocated
for the switch-over, but it should likely take less time.
(If there are problems, this switch-over is being done in a way
which will allow us to go back to the old OpSys.)

I apologize for the somewhat short notice, but the outage of services
should be small (and I want to get this in with sufficient time before
the weekend).

Sincerely,
Scott
