- to be informed when it happens, when it's restored

- to get a planned date for restoration of service

- be told whether there's data loss or not (and what I should have done to 
avoid data loss)



Possible implementations are :

- full redondancy on several sites (well quite expensive), quite compulsory for 
DNS (at least for the secundary)

- no redundancy : means of information are indirect (currently linuxfr is quite 
good), if you still could have sent a mail to subscribers of gna project ML it 
would have been better

- partial redundancy : alternate hosts are available and can  provide minimal 
service (see below)



For example, you could have a www.gna.org hosted on another server :

- if www is unavailable, people go directly to gna.org

- if gna.org (projects) is unavailable, people go to www.gna.org and see what 
happened

=> it's interesting as it does not require any DNS change (which can be long to 
propagate...)



For hosting, you may ask several LUGs, maybe one can provide you with limited 
hosting :

- a homepage for information (users have to find something interesting there, 
or they will forget this URL...)

- maybe a wiki (as was done with tuxfamily.org...)

- perhaps a ML for emergency situations (that project admins are advised to 
subscribe to)



Last : for backups, they should be externalized if possible - either on user 
side : for cvs that's easy (but not for support/bugs...)

- or by server side : maybe a regular rsync (but once gna grows it becomes more 
and more heavy...) 



Maybe there's descriptions of procedures / implementations of this already on 
the web ? other than what I've already done...

Summary:  emergency homepage

Original Submission:  We definitely need an emergency homepage, as suggested by 
Baud123, to be able to inform user easily in case all system go offline. This 
page must be on another location that gna machines (otherwise it would probably 
not help much). An account on this machine should be accessible through ssh to 
gna admins + virtual domain.
We could set emergency.gna.org -- if we use a gna address, it means that the 
secondary DNS must be a working thing.

I was not far for my previous request, as it was support #218 : reread the 
(full) discussion...
