as if most IT systems couldn't be brought down with one wrong person getting sudo access on a domain controller or such – yes, you can protect against maid pulling the power cable of the root DNS server, can't protect against the authoritative root server advertising empty or wrong root zone – there needs to be a single source of truth, but you need a good process/syste how it is updated, which appears to be lacking in Galileo. So, yes, that's a minor kink compared to overall complexity of the system.
and it does look like they did have backups to restore, but because of the precision necessary, and given that the satellites are in in non-inertial reference frames, it does mean that getting it all back synchronised isn't a matter of seconds
