I think we need a public IP because OSGeo admins will be the ones
managing the backups and it would be fairly inconvenient to have to
tunnel through another machine to get there. Also it needs to be able to
talk to all of our Ganeti VMs, so unless we're going to add a second
backend bridge that's not super useful.

Yes, long term redundant power is part of what we bought the PSU for, I
understand that won't be implemented right away.

I'm still discussing with my team if this should be ganeti based or just
direct OS on the metal. Will try to get back an answer soon, might be
hard as most of them are at FOSS4G conference in the UK right now
(OSGeo's main conference every year).

Thanks,
Alex
