[vsnet-grb-info 4892] Power outage for Swift data, HEASARC, and part of GCN Circulars

[GCN Circulars]

TO:  All people interested Swift Data and GCN                     13 July 07
RE:  Service outage due to electrical power upgrades


A power outage is planned for tonight and tomorrow that will take
the Swift Data Center off-line (including access to Swift quick look data),
prevent access to HEASARC web pages (including access to Swift data),
prevent access to GCN web pages,
and interrupt normal e-mail service to most of the Swift science team at GSFC.

The GCN Notices will continue to be distributed.  The GCN computer and routers
are on a separate power circuit.

However, the GCN Circulars will have some difficulties.  Reviewing the traceroutes
of recent Circular submissions shows about 1/3 of them went though a machine
that will be in the power-shutdown (2/3 went straight to the GCN computer).
(I could not determine why there was a difference between the two groups of
submissions.)  So please note that if you submit, you might be in the 1/3 group.
For this 20-hour interval, if you submit and do not receive back the usual
success/problem preport email, do not submit it again.  The lack of a return
probably means you are in the 1/3-group.  If you send in a second submission,
they will both queue up, and ten when power is restored both copies will be distributed.

These systems should start going off line at 22:00 UT July 13th (today),
and should begin to be restored tomorrow July 14th at about 17:00 UT.
